The United States Anti-Doping Agency (USADA) has notified Brock Lesnar of a potential doping violation stemming from one of his tests prior to UFC 200 on July 9.
The USADA confirmed that Lesnar’s out-of-competition drug test on June 28 was the sample that appears to have tested positive.
The UFC acknowledged that they had received the news of Lesnar’s potential doping violation, but said that since they only came to know about it on Thursday, there was no reason to pull Lesnar from his UFC 200 bout with Mark Hunt, which he won via unanimous decision.
“The UFC organization was notified today that [USADA] has informed Brock Lesnar of a potential anti-doping violation stemming from an out-of-competition sample collection on June 28,” a UFC statement said. “USADA received the testing results from the June 28 sample collection from the WADA-accredited UCLA Olympic Analytical Laboratory on the evening of July 14.”
The Nevada State Athletic Commission will look into the possible doping violation with USADA as Lesnar’s fight was held in Las Vegas.
Lesnar had not competed in the UFC since December 2011 prior to his fight with Hunt. According to the UFC, returning athletes must be tested over a four-month period and while the promotion waived this requirement for Lesnar, he still submitted eight tests to USADA.
Lesnar’s potential doping violation comes after interim light heavyweight champion Jon Jones tested positive for a banned substance. With Jones’ “B” sample also having tested positive, he now faces a two-year ban.
