It was confirmed on Tuesday night that “The Spider” had both drostanolone and androstane in his system during pre-fight testing conducted by the Nevada Athletic Commission in January. Neither result was made available prior to Silva fighting – and defeating – Nick Diaz at UFC 183.
“I’ve been competing in this sport for a very long time,” the statement read. “This is my nineteenth fight in the UFC. I have been thoroughly tested many times and have never had a positive drug test.
“I have not taken any performance-enhancing drugs. My stance on drugs is, and will always be, the same. I’m an advocate for a clean sport.”
Silva continued, saying he is “consulting with my advisors right now to explore all of my options and intend to fight this allegation and clear my name. I will not make any further comments until my team advises me to do so.”
He was making his return to the Octagon for the first time since 2013 when a broken leg stopped a title fight with Chris Weidman.
