As noted, the UFC announced Friday night that the U.S. Anti-Doping Agency informed Brock Lesnar on a potential Anti-Doping Policy violation from an out-of-competition sample collection taken on June 28, 2016.
We reached out to WWE for comment. They sent us the following statement, noting that Lesnar will be wrestling at SummerSlam on August 21st:
"Brock Lesnar has not performed for WWE since WrestleMania and is not scheduled to return until Sunday, August 21."
Update 10:52 PM ET: WWE.com reported on Lesnar's potential violation and posted the same statement they sent us above.
