Frank Mir says he never took any performance-enhancing drugs and did not take what came back in his positive drug test.
The former UFC heavyweight champion was flagged Friday by USADA for a potential UFC anti-doping policy violation. The possible violation comes from an in-competition sample taken from Mir the day of his main event fight against Mark Hunt at UFC Fight Night 85 in Brisbane, Australia.
In a statement Mir released Friday night on social media, he said that he doesn't know how he could have tested positive for any banned substance and he denies the use of any PEDs.
