Anderson Silva Refutes Positive Drug Test

Following his UFC 183 unanimous decision victory over Nick Diaz, it was revealed that Anderson Silva had failed a January 9th out-of-competition, pre-fight drug test for two types of performance enhancing drugs.

However, it seems that Silva is refuting the results of the test, and according to Dr. Marcio Tannure, who serves as Silva’s doctor and is also the medical director of the Brazilian MMA Athletic Commission, Silva claims that he did not take drostanolone or androstane.

Here’s what Dr. Tannure told Band News radio:

“Anderson told me he’s disappointed, upset because he didn’t use steroids. He will ask for the confirmation test because he believes the only explanation is a contamination or a mistake from the lab. He told me: ‘I have an impeccable career history and I wouldn’t want to tarnish my image.’

It’s too soon to judge. He has the right to a confirmation test and two other results. The Nevada Athletic Commission hasn’t talked yet, and the press is already judging him. The process isn’t over yet. If the whole process was already over, he would have already been suspended.”
