News broke yesterday that both Stephan Bonnar and Dave Herman tested positive for banned substances following their respective bouts at UFC 153. Bonnar popped for the anabolic steroid Drostanolone, while Herman was busted for marijuana. Since there was no commission in Brazil, the UFC handled the testing themselves. They issued a statement regarding the issue, and said both men admit to taking the banned substances:
"Stephan Bonnar and Dave Herman tested positive for banned substances following their bouts at UFC 153. The UFC has a strict, consistent policy against the use of any illegal and/or performance-enhancing drugs, stimulants or masking agents. Both fighters have admitted taking the banned substances and have orally agreed to suspensions. Once the suspensions have been reduced to written agreements, the results of their tests and the agreed upon suspensions will be sent to the Association of Boxing Commissions official record-keeper so other jurisdictions will be on notice."
This was the second offense for both men. Bonnar tested positive for a different steroid following UFC 62, while Herman was caught by a pre-fight drug test before a planned bout with Mike Russow last year. Marijuana was the substance he popped for that time as well, though he denied using it. UFC president Dana White said that Bonnar is officially retired following his UFC 153 loss to Anderson Silva, while Herman's UFC career hangs in the balance with three straight losses on his record.
