Professional fighter Brock Lesnar notified the UFC of his retirement from MMA, a UFC spokesperson confirmed with MMA Fighting on Tuesday.
That means the 39-year-old will be taken out of the USADA drug-testing pool; he is no longer officially on the UFC roster, according to USADA spokesperson Ryan Madden.
“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 said. “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 was slapped with a one-year suspension last month after testing positive for a banned substance called clomiphene two times over the summer.
After a five-year hiatus from the MMA, Lesnar returned in July for UFC 200, where he squared off in a bout against Mark Hunt. Though he took down Hunt, Lesnar ended up failing an out-of-competition drug test prior to the fight and then another on the night of the fight.
Lesnar has been doing his regular gig with his career in WWE, and will be participating at the upcoming WrestleMania 33 event which takes place on April 2 in Orlando.
