According to his doctor Marcio Tannure, who is also the medical director of the Brazilian MMA Athletic Commission (CABMMA), Silva is devastated with the news, but claims he did not take drostanolone and androstane, the two banned substances found in his system.
“Anderson told me he’s disappointed, upset because he didn’t use steroids,” Dr. Tannure told Band News radio. “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.”
Dr. Tannure was involved in controversial cases in the past. He was once accused by UFC heavyweight Antonio Silva of being responsible for his positive test after a draw with Mark Hunt in 2013. Ten months later, CABMMA was accused by Piotr Hallman of making a mistake in his drug test results, which ended up causing his positive test after a loss to Gleison Tibau in Brazil.
Diaz, who lost to Silva via unanimous decision on Jan. 31, tested positive for marijuana metabolites in the post-fight drug test.
