Anderson Silva Passed Second Drug Screen On January 19

Anderson Silva’s second out-of-competition (OOC) drug test before his UFC 183 win has come back clean of banned substances.

According to Marc Raimondi of MMA Fighting, the Nevada Athletic Commission (NAC) stated that Silva did not have any banned substances in his system in a test taken on Jan. 19, 2015; 12 days before his return win over Diaz and 10 days after he tested positive for drostanolone and androstane.

Silva is still temporarily suspended for the first failure, but has publicly conveyed that he did not use performance-enhancing drugs (PEDs) and is a staunch opponent of them.

The UFC was also reportedly holding back Silva’s substantial $6 million payday for UFC 183, a report they have since denied.

For his part, NAC executive director Bob Bennett could not say that “The Spider” passing a second test would reduce any potential punishment, but did deem the finding positive:

“I can’t speak for the chairman or be presumptuous in any way or comment on that. It’s not my position. We’re happy to get these results.”

The full test sheet results of Silva’s January 19 test were also released by MMA Fighting, where he apparently he passed both a regular drug screen and a human growth hormone (HGH) test.

It remains uncertain as to what bearing these second test results will have on Silva’s punishment, but it definitely is odd that he was clean of banned substances just 10 days after his original failed OOC test.

Drostanolone can stay in an athlete’s system for up to two months after use.

Adding more intrigue to the entire situation, NAC chairman Francisco Aguilar told Ariel Helwani that the second drug test’s results came back on February 2, one day before the results of the first drug test were released on February 3.
