Anderson Silva is an MMA legend by anyone’s definition.

He scored historic victories in the UFC, PRIDE, and Shooto — becoming the longest reigning middleweight champion in UFC history. Among his accolades, Silva holds the UFC record for most consecutive title defenses of any champion.

Then his reign came to an end — losing both of his last championship bouts by ugly TKO and KO losses, including a 2013 leg break which appeared to have ended his career.

The highs have been high, and the lows low — but perhaps, never as much as in the last two weeks.

Silva won his emotional comeback bout against Nick Diaz at UFC 183 on January 31. But two days later, it was revealed that he had tested positive for random out-of-competition drug testing conducted by the Nevada Athletic Commission.

Silva tested positive for steroids drostanolone and androsterone on tests conducted January 9.

Now, results have come back for his second out-of-competition tests, which took place on January 19 — and those, it was revealed yesterday by MMA Fighting, have come back negative.

“We’re happy to get these results,” Nevada Athletic Commission Executive Director Bob Bennett said.

The low side to this, of course, is that it’s entirely possible Silva was “cycling” any performance enhancing drug use in time to pass.

Silva is currently under temporary suspension, and will likely will called before the NAC in the next several weeks.  As reported yesterday here at Caged Insider, he has already been removed from his coaching duties for the fourth season of The Ultimate Fighter: Brazil.
