Brock Lesnar has officially ended his MMA career. A rep from MMAFighting.com had said that Lesnar told UFC that he was done with MMA for good.
Brock Lesnar was/is suspended for a year by the USADA after he had failed two drugs tests for UFC 200 and would have been eligible to fight again in July. Instead, he's retiring from the sport.
He still has to serve the remainder of the suspension if he did decide to come on back in MMA again, though. Around August, Lesnar had told TMZ Sports he was considering another fight, but clearly, things have changed now.
