Earlier this week it was revealed that MMA legend Mirko ‘Cro Cop’ Filipovic had retired from MMA competition ahead of his ‘UFC FN: Seoul’ bout against Anthony Hamilton later this month.

While Cro Cop blamed a lingering shoulder injury for his retirement, the UFC announced that he had also potentially violated the USADA rules.

They released a statement which was obtained by MMAJunkie:

“UFC announced today that a scheduled bout between Mirko Cro Cop and Anthony Hamilton in Seoul, South Korea has been canceled. The U.S. Anti-Doping Agency (USADA) has notified both Mirko Cro Cop and UFC that he has been provisionally suspended at this time due to a potential Anti-Doping Policy violation.

USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case involving Cro Cop. Additional information will be provided at the appropriate time in the process.”
