Not only did Anderson Silva fail an out-of-competition drugs test in the weeks prior to UFC 183, the Nevada State Athletic Commission have now revealed that he also failed his post-fight test too.

We previously reported on his failed test on January 9th in which he tested positive for the performance enhacing substances drostanalone and androstane. Despite that he would later pass another test on January 19th, a little under two weeks before his fight with Nick Diaz.

However, on January 31st, the night of the fight in Las Vegas his post-fight urine test again showed traces of drostanolone and in addition to that he also tested positive for oxazepam and temazepam, substances which are used to treat anxiety and insomnia, respectively.

News of Silva’s latest test failure comes on the day that an NSAC hearing is expected to result in the fighter being temporarily suspended while waiting for an official hearing sometime in March.

It had been anticpated that Silva would have to serve a nine month suspension for his initial failed test, but it’s not clear at this time whether NSAC will seek to extend tht due to the results of his post-fight test.

The UFC will also be holding a press conference of their own tomorrow to address the subject of PED’s after a string of high-profile fighters testing positive for drugs since the turn of the year.

For the record, after news first broke of his out-of-competition test failure earlier this month Silva categorically denied having used PED’s and stated that he was, “an advocate for a clean sport.”

The test results suggest otherwise however and the reputation of arguably the sport’s greatest ever fighter may now be forever tainted.
