Following a UFC 120 preliminary card loss to Rob Broughton, Brazilian heavyweight Vinicius Quieroz (5-2 MMA, 0-1 UFC) tested positive for the banned substance Stanozolol.
Main event fighters Michael Bisping and Yoshihiro Akiyama were both screened, as were six fighters selected on a random basis. Quieroz was the only fighter to test positive.
According to the UFC's U.K. president, Marshall Zelaznik, Quieroz forfeited an undisclosed discretionary bonus from the UFC and has also been released from the promotion. The UFC will also relay the findings to the Nevada State Athletic Commission, which could affect Quieroz's ability to gain a license to fight in the U.S.
