Fabricio Werdum has been suspended for two years by USADA for an anti-doping violation stemming from an out-of-competition sample collected on April 25.
The former UFC heavyweight champion tested positive for the anabolic steroid trenbolone and its metabolite epitrenbolone in a urine screening conducted by USADA. Werdum's two-year sanction is retroactive to May 22, the date his provisional suspension began.
Werdum had been expected to face Alexey Oleynik in the UFC Fight Night Moscow headliner before his failed drug test. Instead, Mark Hunt will square off against Oleynik in the promotion's Russian debut on Saturday.
