Antonio Silva on Anderson Silva: 'I am absolutely sure that he is not guilty of anything'

After a legion of UFC fighters came out to express their disappointment in Anderson Silva for failing a drug test prior to UFC 183, fellow Brazilian, Antonio "Bigfoot" Silva, is convinced of "The Spider's" innocence.

"I am absolutely sure that he is not guilty of anything," Bigfoot told Globo, as translated by MMAMania.com's Alex Schlinsky. "I think he must have made use of something on the orders of the doctor. He was the victim in this doping. I think people upstairs (the Commission) need to see that. It is not the first case of this doctor (Marcio Tannure). They need to see who the athletes are and who is leaving these problems."

Bigfoot has had problems with Dr. Marcio Tannure in the past, blaming the medical director of the Brazilian MMA Athletic Commission (CABMMA) for giving him too high a dose of testosterone replacement therapy (TRT) prior to his fight with Mark Hunt. The UFC has since banned the use of TRT entirely. 

"I had a problem with this doctor and I ended up being suspended nine months for doping. It was the time of the TRT. I made an application to replace the hormone at the time and was released. I knew what he was doing completely and it was allowed, but he gave me a higher dose than my body needed. No evil desire, but do not want on my side."
