Doctor Says Anderson Silva Denies Taking Steroids
Former UFC middleweight champion Anderson Silva has yet to make any public comment since it was revealed that he tested positive for two anabolic steroids prior to his UFC 183 bout with Nick Diaz. His doctor, however, has spoken publicly about the situation, saying that Silva denies having knowingly taken steroids.
Silva’s positive results for Drostanolone and Androstane stem from a Jan. 9 out-of-competition drug test. The results of that test were not reported to the Nevada Athletic Commission until Tuesday, Feb. 3, three days after Silva won a unanimous-decision victory over Diaz.

While the MMA world is up in arms, Silva isn’t talking yet, but his doctor, Marcio Tannure, is talking. Besides being Silva’s doctor, Tannure is also the medical director of the Brazilian MMA Athletic Commission (CABMMA).
“Anderson told me he’s disappointed, upset, because he didn’t use steroids,” Tannure told Band News radio, according to a report from MMAFighting’s Brazilian reporter Guilherme Cruz. “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 continued. “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.”
The process has only just begun, but Silva has been temporarily suspended due to the initial positive result. Nevada Athletic Commission director Bob Bennett confirmed as much to MMAWeekly.com on Wednesday.
Silva still has the option to request his B test sample be tested in an attempt to refute the A sample result, but as of Wednesday that request had yet to be made.

It is also not working in Silva's favor, at least in the court of public opinion, that two of his Black House teammates have tested positive for Drostanolone, one of the two steroids that were indicated in Silva’s initial test results.
Kevin Casey, at UFC 175, and Brian Ortega, at UFC on FOX 12, both tested positive for Drostanolone last July. They were both fined, suspended, and had their victories overturned and ruled no-contests.
Silva is currently slated to be coaching opposite Mauricio “Shogun” Rua and filming The Ultimate Fighter Brazil 4. The UFC has yet to comment on how this situation will affect his participation on the show.
