Former UFC Heavyweight Champion Frank Mir was the latest fighter to fail a USADA drug test, and possibly faces a two-year suspension. USADA found oral turinabol metabolites in his system during an out of competition drug test.
Mir says that he didn't knowingly take the anabolic steroid, but that if he does get suspended for two years it's likely his last time fighting.
