The UFC announced Friday that the U.S. Anti-Doping Agency has informed Brock Lesnar of a possible doping violation stemming from a sample collected 12 days before his UFC 200 victory over Mark Hunt.

"The UFC organization was notified today that the U.S. Anti-Doping Agency (USADA) has informed Brock Lesnar of a potential Anti-Doping Policy violation stemming from an out-of-competition sample collection on June 28, 2016," UFC said in a statement. "USADA received the testing results from the June 28, 2016 sample collection from the WADA-accredited UCLA Olympic Analytical Laboratory on the evening of July 14, 2016.

"USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case. It is important to note that, under the UFC Anti-Doping Policy, there is a full fair legal review process that is afforded to all athletes before any sanctions are imposed."

Lesnar, in a statement to the Associated Press via ESPN, said "we will get to the bottom of this."

Prior to UFC 200, Hunt called out Lesnar for steroids use, accusing the former UFC heavyweight champion of being "juiced to the gills." In response to Hunt's claim, Lesnar took a direct approach.

Brock Lesnar responds to Mark Hunt's PED accusations: 'I'm a white boy and I'm jacked, deal with it'

“I’ve been dealing with that my entire life,” Lesnar said on a media conference call days before UFC 200. “I’m a white boy, and I’m jacked. Deal with it. What do you want me to say? I’m a white boy, and I’m jacked. Deal with it.”

On Friday, Hunt told MMAFighting that he has asked the UFC for half of Lesnar's purse — reportedly $2.5 million before pay-per-view buys factor in — or to be released from his contract effective immediately.

"The cheaters get a slap on the wrist and walk off," Hunt told the website. "What penalty or deterrent is there to make them think twice? Nothing. And the (Nevada Athletic Commission), why should these (expletive) get anything? They are not the ones who had to fight with Lesnar or lose (to him). I lost."

Lesnar, in his first UFC fight since December 2011, scored a unanimous decision win over Hunt. The WWE star said afterward that he would perform at the company's SummerSlam pay-per-view on Aug. 21, holding off on any decision to continue his UFC comeback until after that date.

“Brock Lesnar does what Brock Lesnar wants to do,” Lesnar told reporters after UFC 200. "I believe that my future is already laid out for the next month. I'm doing SummerSlam against Randy Orton. Once the dust settles there, I don’t know what I’m going to do."

WWE, which gave Lesnar permission to fight at UFC 200, has its own PED testing policy as part of its wellness program. It's unclear if Lesnar's possible USADA violation will affect his standing for SummerSlam or beyond with the company.

"Brock Lesnar has not performed for WWE since Wrestlemania and is not scheduled to return until August 21," WWE said in a statement issued to MMAjunkie.
