Former UFC heavyweight Brock Lesnar appears to have fought his last bout in the UFC if reports are correct.

MMA Fighting reported on Tuesday that:

“Brock Lesnar has made no official announcements, but he has notified the UFC of his retirement from MMA, a UFC spokesperson confirmed with MMA Fighting on Tuesday.”

Lesnar was recently removed from the USADA drug testing pool and subsequently from the UFC’s online roster. The WWE mega-star was slapped with a one-year suspension by USADA last month following two positive tests for clomiphene last summer. Reports suggested that Lesnar could have returned following serving his MMA ban after July 15, 2017, but this looks to have been proven as false information.

Lesnar was a former UFC heavyweight champion, and a popular figure with fans. Should the wrestler backtrack on retirement plans, he would need to serve the remaining five months of his initial suspension, which would begin from any return drug-testing pool:

“Pursuant to the UFC Anti-Doping Policy, all UFC athletes serving a period of ineligibility for an anti-doping policy violation are required to remain in the USADA registered testing pool and make themselves available for testing in order to receive credit for time served under his or her sanction,” USADA’s press release regarding Lesnar’s sanction stated. “Furthermore, if an athlete retires during his or her period of ineligibility, the athlete’s sanction will be tolled until such time the athlete notifies USADA of his or her return from retirement and once again makes him or herself available for no-advance-notice, out-of-competition testing.”

Lesnar’s only fight since an initial departure from the UFC almost five years ago came in his victory against Mark Hunt at UFC 200. Lesnar got the nod from judges against “The Super Samoan” but the result had been voided by the Nevada Athletic Commission (NAC) in December.
