The UFC has announced that light heavyweight fighter Thiago Silva tested positive for marijuana metabolites following his bout at UFC on FUEL TV 5 in Macao.
Since there is not an athletic commission in China, the UFC acted as the regulatory body and Silva has agreed to participate in a drug-rehabilitation program and has been suspended six months.
“Thiago Silva tested positive for marijuana metabolites following his bout at UFC on FUEL TV in Macau,” the UFC said in a statement. “The UFC organization has a strict, consistent policy against the use of any illegal and/or performance-enhancing drugs, stimulants or masking agents. Silva has admitted to taking the banned substance and has agreed to participate in an approved drug-rehabilitation program and serve a six-month suspension retroactive to the November 10 event. He must pass a drug test upon completion of the suspension before receiving clearance to fight again.”
Silva (15-3, 1NC) defeated Stanislav Nedkov bu submission in the third round of UFC on FUEL TV 5 earlier this month and the UFC did not announce if the fight will be declared a no contest. For his win over Nedkov, he won the submission of the night bonus and it was the first time he won a fight night bonus.
This is the second time in his career that he has tested positive for a banned substance, with the first time coming after UFC 125. After his win over Brandon Vera, the Nevada State Athletic Commission announced that the urine submitted by Silva was not consistent with human urine. After admitting to not submitting his urine, he was suspended one year by the commission and returned to the UFC earlier this year.
