Earlier this evening (July 15, 2016), the UFC announced Brock Lesnar had been informed of a potential USADA anti-doping violation. The violation dates back to an out-of-competition drug test administered late last month on the 28th of June. It was also one of eight drug tests that Lesnar had taken inside of four weeks leading up to UFC 200 on July 9.
With Lesnar being under contract with them still, the WWE released a statement on the situation via their Twitter:
“Brock Lesnar has not performed for WWE since WrestleMania and is not scheduled to return until Sunday, Aug. 21.”
