Anderson Silva tested positive for drostanolone metabolites during an out-of-competition drug test ahead of his UFC 183 bout with Nick Diaz, according to a statement released by the Ultimate Fighting Championship.
Additionally, NAC Executive Director Bob Bennett informed MMAFighting.com that traces of androsterone, an endogenous steroid hormone, were also found in Silva’s system. The NAC is expected to conduct further testing to confirm Silva’s preliminary results; no punishment has been set for the ex-middleweight champion. The 39-year-old Brazilian had never previously failed a drug test during his UFC tenure. Silva was out of action for more than a year after suffering a gruesomely broken leg in a loss to Chris Weidman at UFC 168. He returned to the Octagon at UFC 183, taking a five-round unanimous verdict over Diaz in the main event at MGM Grand Garden Arena in Las Vegas.
“Anderson Silva has been an amazing champion and a true ambassador of the sport of mixed martial arts and the UFC, in Brazil as well as around the world. UFC is disappointed to learn of these initial results,” the statement read. “The UFC has a strict, consistent policy against the use of any illegal and/or performance enhancing drugs, stimulants or masking agents by its athletes.”
It was later revealed that Silva also failed a post-fight screen. The former middleweight champion tested positive for Oxazepam and Temazepam in a urine test administered on Jan. 31. Oxazepam is used to relieve anxiety, while Temazepam is an anti-insomnia medication. In addition, “The Spider” again tested positive from drostanolone metabolites.
