Brock Lesnar has been given a one-year suspension by USADA.
The WWE superstar and former UFC heavyweight champion tested positive for clomiphene, an estrogen-blocker, in both an in-competition and an out-of-competition drug test leading up to his bout against Mark Hunt at UFC 200 in July.
In December, Lesnar was also given a one-year suspension by the Nevada State Athletic Commission and fined $250,000. His unanimous decision win over Hunt was overturned to a no-contest.
Both year-long sanctions take effect starting July 15, 2016, the day that Lesnar was provisionally suspended by USADA.
The statement released by USADA says that a fighter must remain in the testing pool during their period of ineligibility, and if they officially retire during their suspension, they must continue their suspension if they choose to return. Given the current situation, it seems more likely than not that Lesnar will no longer be competing in MMA.
