Brian Bowles failed his UFC 160 drug test due to an elevated testosterone to epitestosterone (T/E) ratio.
UFC 160 took place at the MGM Grand Garden Arena in Las Vegas and was headlined by a heavyweight title rematch pitting Cain Velasquez against Antonio Silva. Velasquez once again triumphed over “Bigfoot,” finishing the Brazilian with strikes just 81 seconds into the bout.
A former World Extreme Cagefighting bantamweight champion, Bowles competed on the UFC 160 undercard, suffering a second-round technical knockout to fellow WEC alum George Roop. The loss marked the second straight setback for the injury-plagued 32-year-old, who had not competed since November 2011 before returning to the Octagon last month against Roop.
