UFC heavyweight Frank Mir was handed a two-year suspension by the US Anti-Doping Agency (USADA) on Friday after multiple violations of the UFC Anti-Doping Policy.
According to the USADA, Mir tested positive for a banned substance during an in-competition test on March 20 last year – the day of his heavyweight bout against Mark Hunt.
The agency was able to find the substance in Mir’s sample by using a new detection method developed by a WADA-accredited lab in Tokyo.
The new finding prompted USADA to reanalyze Mir’s previously collected samples, in which they discovered an out-of-competition test on February 5, 2016, was also positive for the same prohibited substance.
That February test had previously been reported as a negative test.
Mir’s suspension retroactively began on April 8 last year (the date he was provisionally suspended by USADA) and will run through April 2018.
The 37-year-old has previously stated that he would retire if he was handed a two-year suspension.
If that proves to be the case, then his first round knockout defeat to Hunt more than a year ago will be his final foray into the Octagon.
