MMAFighting.com is reporting that Brock Lesnar has notified the UFC that he has retired from the sport of mixed martial arts and the news was confirmed by a UFC spokesperson.
With his retirement, Lesnar was struck off the USADA drug-testing pool, so officials from the USADA cannot randomly show up at his house to drug test him. All UFC fighters are subject to random out-of-competition testing throughout the year.
When Lesnar returned for UFC 200 last July, there was an uproar because he was supposed to be entered into a drug-test pool at least five months prior, but since the announcement was a surprise, the UFC made use of their under extraordinary circumstances waiver that allowed Lesnar to fight anyway. Lesnar was tested six times leading up to the show in a span of a few weeks and ultimately failed two. Those failures landed him a $250,000 fine and a one-year suspension and his win was turned into a no contest. The former WWE and UFC champion has denied knowingly taking the substance although he did not comment much about it publicly.
Lesnar retires with a record of 5-3-1 and one reign as UFC Heavyweight champion. Just days before WrestleMania 31, Lesnar told ESPN that he had signed a new WWE deal and retired from MMA, only to return a year later for a massive payday.
