Brock Lesnar

Brock Lesnar in 2000 signed a 7-year £36.5m deal worth around £5.2m-per annum. However following the Rey Mysterio match at WrestleMania 22, Lesnar stated in advance he wants to leave WWE to pursue an MMA career, McMahon granted his request. An agreement was reached between the two that his £5.2m per annum contract for 2007 was cancelled and 2006 was halved, leaving in "good terms" and did not rule out a return to the WWE.

Brock Lesnar signed a 3-year deal in March 2012 until March 2015 with Lesnar only working 6 wrestling dates which were the Big 4 PPV's (Royal Rumble, WrestleMania, Summerslam and Survivor Series) and the the 2 Saudi shows (his TV appearances do not count, if he was to wrestle it would count), Lesnar returned to WWE on April 2, 2012, on Raw, as a heel, by confronting and delivering an F-5 to John Cena. As 3 of the six dates he agreed to do already happened this freed him to work 3 other dates (Extreme Rules, Great American Bash and Night of Champions)

In 2015 Brock Lesnar signed a 3-year contract extension until April 1, 2018. He announced he will not be extended his WWE contract to return to the UFC and MMA. Brock Lesnar was granted a leave of absence by the WWE to train for his UFC 2000 fight with Mark Hunt

Lesnar was suspended for 60 days from the WWE from August 22, 2016 until October 21, 2016 for breaching WWE’s drug policy as they did not tell the WWE about the use of substance (as it was banned) as he was still under contract with the WWE. The reason the ban was not immediate was due to the fact that Lesnar is the WWE Champion and needed to first get the belt off him, the "failed drug test" did not change any plans for Lesnar vs Hero match, Chris Hero was suppose to defeat Lesnar anyway regardless.

MMA career
On April 29, 2006, after the final match of the K-1 World Grand Prix 2006 in Las Vegas, Lesnar stated his intent to join K-1's mixed martial arts league, Hero's. He trained with Minnesota Martial Arts Academy under Greg Nelson and Minnesota Assistant Head wrestling coach Marty Morgan. Lesnar signed the deal in August. His first fight was scheduled against Choi Hong-man of South Korea on June 2, 2007 at the Dynamite!! USA show. However, prior to the match, Hong-Man was replaced by Min Soo Kim. Lesnar submitted Soo Kim with strikes in 1:09 of the first round to win his first official MMA match

Lesnar was originally set to Carwin at UFC 106, then UFC 108, but Lesnar pulled out of the fight both times due to diverticulitis and kept him from training. Lesnar initially sought treatment in Canada, but later told reporters that he had received "3rd World treatment" at a hospital in Brandon, Manitoba and that seeking better treatment in USA saved his life. Lesnar went on to criticize Canadian health care further and stated that he shared his experience to speak "on the behalf of the doctors in the United States that don't want health care reform to happen". After UFC 108 it was revealed that he was suffering from a serious case of diverticulitis, an intestinal disorder, which required surgery. After further diagnosis, Lesnar underwent surgery on November 16 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. Shane Carwin won the Interim Heavyweight Championship defeating Frank Mir at UFC 108.

Lesnar attempted to takedown Overeem but was unable and ate heavy body shots to his surgically repaired stomach, eventually being finished with a liver kick and punches. Lesnar then retired from MMA, mentioning his struggles with diverticulitis and saying "tonight was the last time you'll see me in the octagon". However the bout was overturned to a no-contest due to Alistair Overeem testing positive for elevated testosterone which also violated the terms of his "conditional license" he was granted before the fight

Rumours that Lesnar would return to the UFC once his WWE 2015 contract expires surfaced until March 24, 2015 when Lesnar signed a contract extension with the WWE ending the rumours that Lesnar will return to UFC.

UFC announced on June 4, 2016 that he would return at UFC 200 on July 9. WWE confirmed it had granted Lesnar "a one-off opportunity" to compete at UFC 200 before he would return to the company for SummerSlam on August 21.[284] Lesnar dominated the first and third rounds, battering Hunt with ground and pound in the third to secure the unanimous decision win. He also was paid a UFC record $2.5 million purse.[285][286][287] This record was broken at UFC 202 by Conor McGregor, who was also the previous holder

On July 15, after UFC 200, Lesnar was tested positive for clomiphene, a banned substance on the UFC's anti-doping policy, he was suspended from the UFC by the Nevada State Athletic Commission for 2 years, had his purse withheld ($250,000), and his victory over Hunt was overturned from a victory to a no-contest. Lesnar announced he will take USADA to court due to the fact that Lesnar requested a TUE which was granted. Realizing that they might have a good case compared to Lesnar the two meet and an agreement was reached, the victory will be restored, the pursue will not be withheld and will be cleared of any wrongdoing meaning it will not be on his record (so if he was to commit a doping violation it will be his 1st offence not his 2nd offence). His 2-year ban in December 15, 2016 was reduced to 1-year (December 15, 2017), the reason the ban was kept was simply because Lesnar was under contract with WWE which is not set to expire until March 2018 meaning he will not fight until then, Lesnar himself also confirmed he will not fight anymore fights until his WWE contract expires

(Given that Lesnar would need at least 2 months uninterrupted of a full-time camp to get ready for such a fight, mid-June would figure to be the earliest date likely)

Jon Jones
Jon Jones was banned for 2-years tested positive for Turinabol, an anabolic steroid on January 6, 2015 banning him until January 6, 2017. His KO (head kick and punches) win against Cormier at UFC 182 was overturned to a no-contest.

On July 21, 2019 Jones received a Class B misdemeanour after committing battery for an alleged incident in April 2019 involving a cocktail waitress at a strip club in Albuquerque, the waitress claimed that Jones slapped her, put her in a choke hold and kissed her on the neck, and touched her after she had asked him to stop. He was fined $2,000 and was jailed for 180 days being released on January 17, 2020

On August 22, 2019, Jones tested positive for 2 banned substances; clomiphene (an anti-estrogen substance) and letrozole (an aromatase inhibitor) resulting in a 8-year ban due to it been his 2nd drug violation and taking 2 banned substances. His ban will be uplifted on October 28, 2027. Jones announced his retirement from MMA.

Jon Jones however was in trouble once again with the law this time committing the crime of domestic abuse, In the early hours of September 24, 2021, police were called to the Caesars Palace resort hotel in Las Vegas, Nevada, responding to a domestic incident. According to a police report obtained by news site MMA Fighting, a 911 call was made by a hotel security guard when Jones' youngest daughter requested help, claiming there was a domestic incident between Jones and his fiancée, Jessie Moses. Cops arrived in minutes, cutting Jones off as he was attempting to flee the scene. Officers detained Jones and began to investigate the situation. While officers detained Jones, others went to the room to further investigate and get Moses' side of the story. When they arrived to the room, they observed her with blood on her face and clothing, and with a bump on her lip, consistent with someone who had been struck. Moses stated that Jones had left the hotel to go out with friends while Moses and their children went to sleep, and that when Jones returned, he was belligerent, became agitated, and pulled her hair. She claims that the hair pulling was the extent of the physicality between the two, and claimed that the blood on her face and clothing was from chapped lips. She also declined a temporary protective order against Jones. Police stated that while he was being detained, a belligerent Jones headbutted the hood of the patrol vehicle, leaving a dent, they claimed Jones had made threats and challenged the arresting officers to a fight, and that Jones had said he could break free from of the handcuffs. No attempts at a fight were followed through on, however, and Jones was placed under arrest peacefully after the investigation concluded.

Jones' domestic abuse charge was upgraded from a misdemeanour to a felony charge due to child or minor witnessing the abusive conduct (Jones' daughter admitted to seeing the offence) and being a repeat criminal offender (committing 5 previous offences outside Nevada but Nevada state laws suggest it does not have to just be in Nevada), he was placed as a Category C felony and sentenced to 5 years in prison service in Nevada State Prison and fined $5,000 he will be released on September 24, 2026. Jones' ifghting ban was increase by another 5 years meaning it will be uplifted August 22, 2032
