Brock Edward Lesnar (July 12, 1977) is an Americanprofessional wrestler, actor, a former mixed martial artist and amateur wrestler. He is a former UFC Heavyweight Champion and is ranked the No.5 Heavyweight in the world by Sherdog. Lesnar is an accomplished amateur wrestler, winning the 2000 NCAA heavyweight wrestling championship and placing second in 1999, losing in the finals to 1999 world freestyle wrestling champion and future New England Patriots offensive lineman Stephen Neal.
Lesnar started a career in mixed martial arts and won his first fight in June 2007. He then signed with the Ultimate Fighting Championship (UFC) in October 2007. He lost his UFC debut against Frank Mir. He captured the UFC Heavyweight Championship from Randy Couture on November 15, 2008, then avenged his loss to Mir at UFC 100 to become the Undisputed Champion. After being sidelined from fighting in late 2009 due to diverticulitis, Lesnar returned to defeat the Interim UFC Heavyweight Champion Shane Carwin at UFC 116. Lesnar lost the Heavyweight belt against Cain Velasquez at UFC 121. He was once again stricken with a bout of diverticulitis in May 2011 and had surgery to try to cope with the ailment. In August 2011, Lesnar stated that he is ready to return to fighting in the UFC. Following his loss to Alistair Overeem at UFC 141, Lesnar announced that he has retired from UFC.
Brock Lesnar was born in Webster, South Dakota. He attended Webster High School in Webster, where he had a wrestling record of 33-0-0 in his senior year. Lesnar admits he graduated last of 54 students in his class. Lesnar later attended the University of Minnesota on a full wrestling scholarship for his junior and senior years of college; his roommate was fellow professional wrestler Shelton Benjamin who also served as Lesnar's assistant coach. Lesnar won the 2000 NCAA wrestling championship as a heavyweight after placing second in 1999.
Prior to joining the Minnesota Golden Gophers, Lesnar also wrestled at Bismarck State College in Bismarck, North Dakota. Lesnar finished his amateur career as a two-time NJCAA All-American, 1998 NJCAA Heavyweight Champion, two-time NCAA All-American, two-time Big Ten Conference Champion, and the 2000 NCAA heavyweight champion with a record of 106–5 overall in four years of college.
Lesnar debuted on WWF television on the March 18, 2002 episode of Raw, the night after WrestleMania X8, coming through the crowd and attacking Al Snow, Maven, and Spike Dudley during the course of a match. He was accompanied by Paul Heyman, who was seen giving instructions to Lesnar. When the brand extension was introduced in the WWF, Lesnar was drafted to the Raw brand. Later, Heyman was confirmed to be Lesnar's agent and gave Lesnar the nickname "The Next Big Thing". Brock's first feud was with the Hardy Boyz. Lesnar and Jeff Hardy squared off at Backlash in Lesnar's first official televised match. He won the match by knockout. The next night on Raw Lesnar faced off against Matt Hardy, defeating him in the same fashion. At Judgment Day, Lesnar once again gained the upper hand on the Hardy Boyz before tagging his partner, Heyman, in to make the pin.
In June 2002, Lesnar won the King of the Ring tournament, defeating Rob Van Dam in the final round. This victory earned him a shot at the WWE Undisputed Championship at SummerSlam. On July 22, Lesnar joined the SmackDown! brand. After a quick feud with Hollywood Hulk Hogan in August 2002, Lesnar began feuding with the Undisputed Champion The Rock. At the main event of SummerSlam, Lesnar defeated The Rock to become the WWE Undisputed Champion. With his victory at age 25, Lesnar became the youngest WWE Champion in history (a record that was previously held by The Rock and stands to date). With the WWE Undisputed Championship being defended on both brands, Raw General ManagerEric Bischoff expected Lesnar to be able to return to Raw the following night. However, SmackDown General Manager Stephanie McMahon announced that Lesnar's contract only required him to defend the title on SmackDown!, forcing Bischoff to establish a new world championship for his brand. With the new World Heavyweight Championship on the Raw brand, the now disputed WWE Undisputed Championship simply became known as the WWE Championship.
Lesnar's rapid rise to the top of WWE in 2002 led to a feud with The Undertaker, which involved a match at Unforgiven. It ended in a double disqualification leading to Lesnar retaining the title. The next month, at No Mercy, he faced The Undertaker again, this time in a Hell in a Cell match. Leading up to the match, Lesnar broke the Undertaker's hand with a propane tank. Despite Heyman begging McMahon not to let The Undertaker use his cast as a weapon, the request was denied and the match went on as planned. In a match that saw both wrestlers and even Heyman covered in blood, it ended when Lesnar reversed an attempted Tombstone piledriver into his finishing F-5 maneuver for the win. Six days after his Hell in a Cell match with The Undertaker, Lesnar successfully retained his WWE title in a Handicap match with Heyman at the Rebellion pay-per-view against Edge.
Lesnar's next opponent was The Big Show. Heyman was convinced more than anyone that Lesnar could not win, trying to talk him out of defending the title. Lesnar refused and lost the championship in Madison Square Garden at the Survivor Series pay-per-view to Big Show, Lesnar's first pinfall loss in WWE. When the champion tried to pin the 500-pounder following an F-5, he was betrayed by Heyman who pulled the referee out of the ring allowing Big Show to capitalize and win the title. As a result, Lesnar became a fan favorite. Following Survivor Series, Heyman made it clear that Lesnar would not get a rematch, even going so far as to sneak a special clause in his contract. At the Royal Rumble event in January 2003, Lesnar defeated The Big Show in a qualification match. Lesnar later entered the Rumble as the No.29 entrant where he eventually won by eliminating The Undertaker.
After winning the Royal Rumble match, Lesnar spent the next two months in a scripted feud with WWE champion Kurt Angle, who Lesnar had helped win the title and who was represented by Paul Heyman. Angle had Heyman, and Team Angle (Shelton Benjamin and Charlie Haas) behind him, but Lesnar overcame these opponents. Lesnar regained the WWE Championship in the main event of WrestleMania XIX. Toward the end of the match, he botched a shooting star press; despite having landed the move successfully several times in OVW, in this match he overestimated the distance he was capable of jumping for the move and under-rotated, slamming his head into Angle's side and ribcage. This stunned Lesnar and forced Angle to improvise the finish of the match. Lesnar suffered a severe concussion from the botched move.
Following WrestleMania, John Cena began targeting Lesnar for almost ending his career (by using the F-5 to propel his leg into a ring post) after a previous match between the two. This led to Cena receiving a title match at Backlash in which Lesnar successfully retained the title. Earlier at the Backlash pay-per-view, Big Show had injured Rey Mysterio badly, resulting in Mysterio being carried out on a stretcher. This injury led to Lesnar renewing his feud with Big Show, which led to a Stretcher match at Judgment Day for the title. Lesnar successfully retained his title with help from Rey Mysterio and a forklift. During the scripted rivalry, on SmackDown!, Lesnar lifted Big Show over in a Superplex, which caused the ring to collapse on impact. At Vengeance, Lesnar lost his title to Kurt Angle in a No Disqualification Triple Threat match that involved Big Show.
Prior to SummerSlam, Lesnar became a villain by betraying Kurt Angle, leading to a rematch at the event. Lesnar lost to Angle when Angle made Lesnar tap out to the ankle lock. A second rematch between Lesnar and Angle, an Iron Man match, was later held on an episode of SmackDown!. Lesnar defeated Angle in a match that was said as one of the best in SmackDown! history. Angle slapped on the ankle lock with a few seconds remaining but Lesnar did not tap. Lesnar won with five falls to Angle's four, making him a three-time WWE Champion. Lesnar's first challenger for his newly won title was The Undertaker. Lesnar had previously cost Undertaker the title in a match against then-champion Kurt Angle, which granted him a shot at Lesnar's title. At No Mercy, Lesnar defeated Undertaker in a Biker Chain match.
Lesnar realigned himself with Paul Heyman after Heyman became General Manager of SmackDown! and formed Team Lesnar with Big Show, Matt Morgan, A-Train, and Nathan Jones for a 10-man Survivor Series match at Survivor Series. In the climax of the match, Chris Benoit became the second person to make Lesnar tap out. Lesnar faced Benoit in a singles bout two weeks later for the WWE Championship on SmackDown!, where Lesnar won after Benoit passed out to Lesnar's debuting Brock Lock submission hold.
Feuding with Goldberg and departure (2003–2004)Edit
The Survivor Series event marked the first time Lesnar met Goldberg from the Raw brand, a man to whom Lesnar had been compared due to their similar physiques and undefeated streaks in wrestling. Lesnar claimed in a backstage interview that he could beat anybody in the world, leading to Goldberg interrupting the interview and introducing himself to Lesnar, shaking hands with him before leaving with a staredown. Lesnar followed this rivalry with a feud involving Hardcore Holly. In the storyline, Holly wanted revenge on Lesnar for legitimately injuring his neck during a previous match between the two in 2002 which left Holly in need of neck surgery and out of action for a year. At the Royal Rumble in 2004, Lesnar defeated Holly to retain the WWE Championship. Later in the Royal Rumble match, Lesnar attacked Goldberg and delivered an F-5, enabling Kurt Angle to eliminate him.
In February, Lesnar faced Eddie Guerrero for the title at No Way Out. During the match, Goldberg interfered in the match, allowing Guerrero to capitalize and pin Lesnar after a frog splash to win the WWE Championship. The match set up an interbrand match for WrestleMania XX between Lesnar and Goldberg. During the feud with Goldberg, Lesnar was at odds with Stone Cold Steve Austin, who was shown suggesting to Goldberg that he attack Lesnar at No Way Out. When Lesnar attacked Austin on Raw and stole his four-wheeler, Austin was inserted as the special guest referee for the Wrestlemania match. Behind the scenes, it was widely known that the match would be Goldberg's last in WWE. Only a week before Wrestlemania, however, rumors surfaced that Lesnar, too, was leaving in order to pursue a career in the National Football League. As a result, Lesnar's match with Goldberg became a fiasco as the fans at Madison Square Garden jeered and heckled both wrestlers vociferously. Goldberg gained victory after delivering a spear to Lesnar and both men subsequently received Stone Cold Stunners from Austin.
On October 8, 2005, Lesnar won the IWGP Heavyweight Championship in a three-way match at a New Japan Pro Wrestling show in the Tokyo Dome, which included the then-champion Kazuyuki Fujita and Masahiro Chono. He won the match by pinning Masahiro Chono after an F-5, which he had renamed the Verdict, since WWE owns the trademark on the F-5 name. After the match, he stated that this name was referring to his lawsuit against WWE. The match was his first pro wrestling match since leaving WWE. Lesnar is one of the few American wrestlers to have held this title.
On December 6, WWE filed a motion for a temporary restraining order to prevent Lesnar from continuing to work with NJPW, but the court did not grant it, and thus Lesnar had two non-title victories against Manabu Nakanishi and Yuji Nagata. Lesnar successfully defended his championship on January 4, 2006, against former champion Shinsuke Nakamura. On January 13, WWE once again filed an injunction against Lesnar to stop him from defending the IWGP Heavyweight Championship on March 19. Evidently this was not enforced (nor granted), as he went on to have a tag team match with Shinsuke Nakamura against Akebono and Riki Chōshū at the Sumo Hall on February 19, which was won after a Verdict to Chōshū. On March 19, at the Sumo Hall, Lesnar retained his championship against former Sumo Wrestling Grand Champion Akebono when Lesnar hit him with the championship belt and a DDT. Lesnar went on to successfully defend his title against the winner of the New Japan Cup, Giant Bernard, on May 3, 2006, in Fukuoka. This was the first American vs. American title match in NJPW since Vader vs. Stan Hansen in 1990.
On July 15, 2006, New Japan Pro Wrestling announced that Brock Lesnar had been stripped of the IWGP Heavyweight Championship as he would no longer be returning to defend the title due to "visa issues." A tournament was held on July 16 to determine the new champion, which was won by Hiroshi Tanahashi, the man Lesnar was originally scheduled to face. Lesnar continued to possess the physical IWGP Championship belt until late June 2007.
Approximately one year later, on June 29, 2007, Lesnar defended his IWGP Heavyweight Championship (IGF promoter Antonio Inoki had stated he still viewed Lesnar as the "proper" IWGP Champion, as he was never defeated for the title) against TNA World Heavyweight ChampionKurt Angle in a champion versus champion match. Angle defeated Lesnar with the Ankle lock to win the IWGP Heavyweight Championship as recognized by IGF and TNA. and challenged him to an MMA fight. This was Lesnar's last match as a professional wrestler until 2012.
Lesnar had previously signed a no-compete clause in order to be released from his contract with WWE, which prohibited him from working for any other sports entertainment or mixed martial arts companies before June 2010. Lesnar had anticipated leaving wrestling entirely, but his inability to secure a career in professional football led to him challenging this ruling in court. WWE responded by demanding damages as a result of Lesnar allegedly breaching the agreement by appearing at a New Japan Pro Wrestling show in 2004. In July 2005, the two sides dropped their claims and entered negotiations to renew their relationship. WWE had offered Lesnar a contract, but on August 2, 2005, WWE's official website reported that Lesnar had withdrawn from any involvement with the company. The lawsuit was then entered into settlement on September 21, but talks broke down.
On January 14, 2006, Judge Christopher Droney stated that unless WWE gave him a good argument between then and January 25, he would rule in favor of Brock Lesnar, giving him a summary judgment. This would have enabled Lesnar to work anywhere he wanted immediately. WWE was later granted a deadline postponement. On April 24, World Wrestling Entertainment announced on their official website, WWE.com, that both parties had mutually come to a settlement and on June 12, a federal judge dismissed Lesnar's lawsuit against WWE after both parties requested for the case to be dismissed.
Brock Lesnar returned to WWE on the April 2, 2012 episode of Raw, confronting John Cena and hitting him with an F-5. The next week, General ManagerJohn Laurinaitis revealed that he signed Lesnar to bring "legitimacy" and become the "new face of the WWE" before also announcing that Lesnar would face Cena at Extreme Rules. Cena then interrupted and engaged in a brawl with Lesnar, which resulted in the entire WWE locker room trying to pull them apart and Cena being left bloodied. On April 16, the Extreme Rules stipulation was added to the match. At the pay-per-view, Lesnar would debut a new ring attire, dressed in his MMA gear and 4XL-size gloves he wore in the UFC. He again bloodied Cena with MMA-style strikes, but would ultimately lose the match. The following night on Raw, WWE's Chief Operating Officer Triple H refused to give in to Lesnar's unreasonable contract demands, resulting in Lesnar attacking Triple H and breaking his arm with a kimura lock.
The next week, Paul Heyman made his return as Lesnar's legal representative and claimed that Lesnar was quitting WWE. Heyman would later announce a lawsuit against WWE for breach of Lesnar's contract. At the No Way Out pay-per-view in June, Triple H challenged Lesnar, who was not present, to a match at SummerSlam, which Heyman refused on Lesnar's behalf the following night on Raw. On July 23 at Raw 1000, Triple H's wife, Stephanie McMahon, goaded Heyman into accepting Triple H's challenge against Lesnar. Following this, Lesnar returned and had a brief brawl with Triple H before he was chased from the ring. In a bid to psychologically unsettle Triple H, Lesnar would break the arm of Triple H's best friend Shawn Michaels with a kimura lock on the August 13 episode of Raw. Six days later at SummerSlam, in a match dubbed the Perfect Storm, Lesnar defeated Triple H via submission after once again breaking his arm with a kimura lock. The following night on Raw, Lesnar would crown himself the new King of Kings and then release a tout in which he revealed that he would be departing, due to his victory of Triple H displaying that he had conquered everything in the WWE.
Lesnar returned to Raw on January 28, 2013, confronting Vince McMahon, who was just seconds away from firing Paul Heyman. Despite Heyman's pleas, Lesnar hit McMahon with an F-5, effectively breaking McMahon's pelvis. The following week, Vickie Guerrero revealed herself to be the one who signed Lesnar to a new contract. After, Lesnar confronted and attacked The Miz. On February 25, Lesnar interrupted a match between Mr. McMahon and Paul Heyman, only to get into a brawl with a returning Triple H which resulted in Lesnar's head being split open and requiring 18 stitches. The following week, Triple H issued a challenge to Lesnar for a match between them at WrestleMania XXIX, which Lesnar accepted after Triple H sighned a contract and Lesnar named the stipulation. The following week, Triple H signed the contract and assaulted Heyman, the stipulation was revealed as a No Holds Barred match and Triple H's career was on the line. Lesnar ended up losing the match after Triple H hit Lesnar with a pedigree onto the steel steps. At Raw Paul Heyman made a match at Extreme Rules, a Steel Cage Match, On April 22, Triple H accepted Lesnar's challenge. At the 2013 Extreme Rules, Lesnar won the match via escaping the cage. On the June 17 episode of RAW, Lesnar attacked Punk on behalf of Heyman.
Despite the accusations from Punk, Heyman claimed that he was not behind Lesnar's attack on him. However, in July, Heyman turned on Punk, and claimed that Punk could not beat Lesnar, which led to Lesnar making his return and attacking Punk on the July 15 episode of Raw. The following week on Raw, Punk challenged Lesnar to a match at SummerSlam, which Heyman accepted on behalf of Lesnar. On the August 5 episode of Raw, Lesnar came out and brawled again with Punk; Lesnar ultimately got the upper hand on Punk, despite Punk putting on a valiant effort. Punk then got revenge the following week by attaking Lesnar with a camera and a steel chair after Heyman tried to trap Punk by having him fight both him and Lesnar instead of the scheduled match of Punk versus Heyman. Six days later at SummerSlam, Lesnar defeated Punk in a no disqualification match.
On the December 30, 2013 episode of Raw, Lesnar returned with Paul Heyman to announce his intentions to challenge the winner of the upcoming WWE World Heavyweight Championship match between Randy Orton and John Cena at the Royal Rumble. Lesnar then called out any wrestler who wanted to stop him, which resulted in Mark Henry answering the challenge and the two brawling until Lesnar ended the brawl with an F-5. The follwoing week on Old School Raw, Mark Henry challenged him again only to have Lesnar dislocate his elbow with the Kimura Lock. Follwoing theis, Big Show came out and confronted Lesnar, which resulted in a short physical confrontation between the two. Lesnar defeated Big Show at the Royal Rumble. On the February 24 episode of Raw, Lesnar received a contract to face anyone he wanted at WrestleMania XXX in consolation for not being able to compete foe the WWE World Heavyweight Championship. The Undertaker returned to confront Lesnar and accepted the challenge for a WrestleMania XXX match. Lesnar would ultimately end Undertaker's streak at the event, extending Undertaker's record to 21 wins and 1 loss.
On the July 21, 2014 episode of Raw, he was chosen by Triple H as John Cena's SummerSlam opponent. At Summerslam, Lesnar defeated Cena in an extremely one-sided match to become the WWE World Heavyweight Champion. During the match, Lesnar delivered sixteen German suplexes and two F-5's on Cena. On the August 19 episode of Main Event, Triple H announced that Cena would invoke his championship rematch clause against Lesnar at Night of Champions. Lesnar wound up being disqualified due to Seth Rollins interfering, but Cena thereafter prevented Rollins from cashing in his Money in the Bank contract.
At the Royal Rumble on Jan. 25, 2015, Lesnar defied the odds, silenced the critics and stunned the WWE Universe by conquering both John Cena and Seth Rollins and solidifying his road to WrestleMania as the reigning WWE World Heavyweight Champion. After a bit of controversy following the Royal Rumble Match, Lesnar and the WWE Universe witnessed Roman Reigns earn the right at WWE Fastlane to challenge The Beast at The Show of Shows.
Lesnar was not impressed by his competition, however, and he showed it at WrestleMania by absolutely dominating Reigns for the majority of the main event. When Reigns turned things around and weakened Lesnar, Seth Rollins showed up to have one of the most shocking Money in the Bank cash-ins in history. Rollins made the contest a Triple Threat Match, pinned Reigns, and stole Lesnar's title away from The Beast.
The following night on Raw, a furious Lesnar demanded Rollins hand his WWE World Heavyweight Championship back via his rematch clause that night. When Rollins refused, Lesnar went berserk, destroying the Raw announce team and an innocent cameraman.
Stephanie McMahon was left with no choice but to indefinitely suspend Lesnar, who announced on ESPN's SportsCenter one week earlier that he had re-signed with WWE on a three-year deal. It's unsure when Lesnar's suspension will be lifted, but when it is, it will signal bad news for Rollins and anyone else who dares to get in the path of this now enraged Beast.
Lesnar returned from his suspension sporting a new shirt ("Suplex City") and immediately went after Rollins, who was alone in the ring (Kane and J&J Security initially left). Lesnar attacked Rollins but was ultimately saved by J&J Security & Kane. Lesnar fought off the attack though, smashing Noble into the barricade, breaking a few ribs. His rampage was short-lived, however, as Kane was able to trip him from behind, which led to Rollins torturing Lesnar's leg against the steel post. The following week on RAW, Rollins called out Lesnar, who retaliated by trashing the 55 thousand dollar Cadillac Rollins had bought for J&J Security, which sparked a small brawl outside the car. Lesnar twisted Noble's arm until it broke, and he suplexed Mercury into the car.
On April 28, 2006, Lesnar appeared inside the ring after the final match of K-1 Hero's Las Vegas and announced his intent to join the MMA promotion. He trained with Minnesota Martial Arts Academy under Greg Nelson, and University of Minnesota Assistant Head wrestling coach Marty Morgan. Brock Lesnar announced on August 12 in Las Vegas that he had signed a deal with the K-1 promotion. His first fight was scheduled for June 2, 2007, on the K-1 Dynamite!! USA show against Choi Hong-man of Korea. However, prior to the match, Choi Hong-Man was replaced by Min Soo Kim. Lesnar submitted Min Soo Kim due to strikes in 1 minute 9 seconds of the first round to win his first official MMA match.
During UFC 77, it was announced that Brock Lesnar had reached a deal to fight with the Ultimate Fighting Championship (UFC). On February 2, 2008, Lesnar made his debut with the promotion in an event titled UFC 81:Breaking Point against former UFC Heavyweight Champion, Frank Mir. Lesnar secured an early takedown, but was deducted a point for hitting Mir on the back of the head. Following another takedown by Lesnar, Mir managed to secure a kneebar and force a submission at 1:30 of the first round. Due to the large size of his hands, Lesnar was wearing 4XL gloves for the fight, making him the second man in Nevada's combat sports history to wear such gloves after Choi Hong-man. At UFC 82, it was announced that former UFC Heavyweight Champion and UFC Hall of Fame inductee Mark Coleman would fight Lesnar at UFC 87:Seek and Destroy. Coleman was forced to withdraw from the fight due to a training injury, and Lesnar's opponent was changed to Heath Herring. In the early seconds of the first round, Lesnar dropped Herring with a straight right. For the rest of the fight, Lesnar kept the fight on the ground and went on to win by unanimous decision.
Lesnar's next opponent was Randy Couture for the UFC Heavyweight Championship at UFC 91:Couture vs Lesnar on November 15. Lesnar beat Couture via a technical knockout in Round 2, becoming the UFC Heavyweight Champion.
On December 27, 2008, at UFC 92, Frank Mir defeated Antônio Rodrigo Nogueira for the Interim Heavyweight title and was to face Lesnar for the Undisputed UFC Heavyweight Championship at UFC 98. Immediately after winning the Interim Heavyweight title, Mir found Lesnar in the crowd and shouted at him "You've got my belt."
However, due to a knee injury to Mir, the title unification match with Lesnar that was originally slated to be the UFC 98 main event was postponed. The news broke during the broadcast of UFC 96 that the bout had been cancelled and was replaced by Rashad Evans vs. Lyoto Machida for the UFC Light-Heavyweight Championship." Lesnar won the postponed rematch with Mir at UFC 100 on July 11, 2009, via Knockout after dominating his opponent for the duration of the bout. The win earned Lesnar Beatdown of the Year honors from Sherdog for 2009. It's an award he shares with Anderson Silva after his win over Forrest Griffin. During his post-match celebration, Lesnar flipped off the crowd who had been booing him. He made a disparaging comment about the PPV's primary sponsor Bud Light, claiming they "won't pay me nothin", promoting Coors Light instead. He then stated he might even "get on top of [his] wife" after the show. He would later apologize for his actions in his post-fight press conference, where he held a bottle of Bud Light.
In January 2009, Brock Lesnar signed a supplement endorsement deal with Dymatize Nutrition. A CD containing training footage of Lesnar was included with boxes of Dymatize Xpand and Energized Xpand.
On July 1, 2009, it was reported that the winner of the Shane Carwin vs. Cain Velasquez fight at UFC 104 would face Brock Lesnar in his second title defense on a date yet to be determined; however, the UFC then reconsidered the contendership bout and Lesnar was scheduled to defend his belt against Shane Carwin at UFC 106 on November 21.
On October 26, 2009, it was announced that Lesnar had pulled out of the UFC 106 card in which he was set to face Shane Carwin for the UFC Heavyweight Championship due to an illness. UFC President Dana White said that Brock had been ill for three weeks, claiming he had never been this sick in his life and that it would take him a while to recover; his fight with Carwin was rescheduled for UFC 108 in early 2010. Lesnar initially sought treatment in Canada, but later told reporters that he had received "Third World treatment" from malfunctioning equipment at a hospital in Brandon, Manitoba, and that seeking better medical treatment in the United States saved his life. Lesnar, who describes himself as a conservative and a supporter of the US Republican Party, went on to criticize Canadian-style health care further and said that he shared his experience in an effort to speak "on the behalf of the doctors in the United States that don't want health care reform to happen and neither do I."
On November 4, it was confirmed that Lesnar was suffering from mononucleosis and that his bout with Carwin would have to wait a bit longer, thus the fight for UFC 108 was cancelled. On November 14 at the UFC 105 post-fight conference, Dana stated, "He's not well and he's not going to be getting well anytime soon." and that an interim title match might need to be set up. In addition to mononucleosis, it was revealed that Lesnar was suffering from a serious case of diverticulitis, an intestinal disorder, which would require surgery. After further diagnosis, on November 16 Lesnar underwent surgery to close a perforation in his intestine that had been leaking fecal matter into his abdomen, causing pain, abscesses, and overtaxing his immune system to the point that he contracted mononucleosis. From the level of damage to Lesnar's system, the surgeon estimated that the intestinal condition had been ongoing for around a year.
In January 2010, Lesnar announced on ESPN SportsCenter that he was scheduled to make a return to the UFC in the summer of 2010. A match between Frank Mir and Shane Carwin took place on March 27 at UFC 111 to determine the UFC Interim Heavyweight Champion, and Brock's next opponent. Shane Carwin defeated Frank Mir by KO in the first round, becoming the new Interim Champion. After the fight, Brock came into the ring and stated "It was a good fight, but he's wearing a belt that's a make believe belt, I've got the real championship belt."
Lesnar faced Shane Carwin at UFC 116 to unify the heavyweight titles. After Carwin knocked him down early in the first round, Lesnar survived a ground and pound attack. Early in the second round, Lesnar was able to take Carwin down, attain a full mount, then move into side-control and finish the fight with an arm triangle choke. With the victory, Lesnar again became the Undisputed UFC Heavyweight Champion, earning his first UFC Submission Of The Night and giving Carwin his first loss.
Lesnar's next defense was against undefeated top contender Cain Velasquez on October 23, 2010, at the Honda Center in Anaheim, California at UFC 121. Dana White announced via SportsNation that the UFC would be bringing back UFC Primetime to hype up Lesnar vs. Velasquez at UFC 121. Lesnar was defeated by Velasquez for the UFC Heavyweight Championship via TKO in the first round at UFC 121 on October 23, 2010.
On January 11, 2011, it was revealed that Lesnar would be one of the coaches of The Ultimate Fighter Season 13, opposite to Junior dos Santos, with the two expected to face each other on June 11, 2011 at UFC 131. Lesnar, however, was struck with another bout of diverticulitis and had to withdraw from the bout on May 12, 2011. He was replaced by Shane Carwin who lost against dos Santos at UFC 131.
Lesnar underwent surgery on May 27, 2011, to help battle his problems with diverticulitis. UFC president Dana White said that Lesnar had a 12-inch piece of his colon removed.
ESPN The Magazine, in its May 2011 issue, did a story listing the highest paid athlete based on base salary and earnings for the most recent calendar year or most recent season in 30 sports. Brock Lesnar topped the list for mixed martial artists at $5.3 million, which included his reported bout salaries and estimated pay-per-view bonuses.
In the summer of 2011 Lesnar announced that he was ready to get back into the Octagon, stating that "I feel like a new man, healthy, strong, I feel like I used to feel."
His return match was scheduled to be at UFC 141 on December 30 in Las Vegas against former Strikeforce heavyweight champion Alistair Overeem. Lesnar had to cut weight for the fight in order to meet the 265 lb weight limit and entered the Octagon with a potential title shot at the new champion Junior dos Santos for the match victor. During the match, Overeem targeted his opponent's midsection and was able to land several strikes before delivering a powerful kick that dropped Lesnar to his knee and left him prey to a barrage of punches resulting in the referee stopping the fight and declaring Overeem the winner via TKO at 2:26 of the first round. After the defeat, Lesnar announced his retirement from mixed martial arts, mentioning his struggles with diverticulitis and saying "tonight was the last time you'll see me in the octagon". UFC President Dana White commented that whilst he had no foreknowledge, Lesnar's decision to retire was not a surprise to him.
Lesnar grew up on a farm in South Dakota, and later joined the National Guard at the age of seventeen. In January 2001, Lesnar was arrested for receiving large amounts of what was alleged to be steroids. The charges were later dropped when it was discovered the substances were in fact a legal growth hormone. His lawyer later described the growth hormone as a "vitamin type of thing."
Lesnar has one daughter, Mya Lynn who was born on April 10, 2002, with his ex-fiancée, Nicole. He left Nicole in 2003 in order to begin a relationship with Rena "Sable" Mero who had been recently divorced from Marc Mero. Lesnar and Mero were engaged in 2004, separated in 2005, then reconciled later that year and married on May 6, 2006. Lesnar has one stepchild with Mero: Mariah, a stepdaughter born to Mero and her late husband, Wayne Richardson. The couple had their first child together, a son named Turk in June 2009. The couple had their second child, a son named Duke in July 2010.
Lesnar has numerous tattoos, with the most prominent being a stylized skull in the center of his back and a large sword on his chest.
He is known to be very conservative of his private life and avoids discussing it in interviews:
On December 15, 2011, Lesnar was charged with hunting infractions of a trip to Alberta on November 19, 2010. On a court appearance in Medicine Hat in December 20, two charges were dropped but pleaded guilty to the charge of improper tagging of an animal. Lesnar was fined $1,725 and given a six-month hunting suspension.
