UFC Middleweight Anderson Silva

For someone who claims he’s never taken any banned substances, former UFC middleweight champion Anderson Silva (pictured) sure fails a lot of drug tests.

During Tuesday’s Nevada Athletic Commission meeting, it was announced Silva flunked his UFC 183 post-fight drug test, which was administered by the NAC the night of his January 31 unanimous decision victory over Nick Diaz, for Oxazepam and Temazepam – two prohibited Benzodiazepines, as well as Drostanalone, an anabolic steroid.

This goes along with the pre-fight, out-of-competition drug test he failed on January 9 for Drostanolone metabolites and Androsterone, a form of endogenous testosterone.

However, Silva was clean on his January 19 drug screening.

According to Drugs.com, Oxazepam is used to combat anxiety. It may also be used to treat alcohol withdrawal. The same website reports Temazepam is used to treat insomnia.

The NAC claims they were notified February 3 about the Benzodiazepines results and they were alerted seven days later regarding Drostanolone.

Diaz, who was busted in his pre- and post-fight drug tests for marijuana, was clean for any performance-enhancing substances on all exams.

Outside of a brief statement professing his innocence, Silva hasn’t said anything since his illustrious career was tarnished with these positive tests. The NAC will likely temporarily suspend Silva during Wednesday’s meeting.

A disciplinary hearing that Silva would be required to attend will most likely be scheduled in March.

Silva, regarded by many as the greatest mixed martial artist to ever live, is facing at least a nine-month suspension, fine and having his victory overturned to a no contest.
