Thiago Silva has been suspended six months, and will participate in a drug-rehabilitation program, after testing positive for marijuana metabolites after his UFC on FUEL TV 6 fight, according to a Zuffa statement Wednesday.

Here is the statement below:

“Thiago Silva tested positive for marijuana metabolites following his bout at UFC on FUEL TV in Macau. The UFC organization has a strict, consistent policy against the use of any illegal and/or performance-enhancing drugs, stimulants or masking agents.

Silva earned submission of the night honors at UFC on FUEL TV 6 with his arm-triangle choke of  Stanislav Nedkoz at 1:45 in the third round. Marc Ratner, the UFC VP of regulatory affairs, told MMA Fighting’s Ariel Helwani that the win would become a no-decision, confirming an earlier MMA Junkie report.

It’s not the first time Silva has had issues with post-fight drug tests. He was suspended for a year by the Nevada State Athletic Commission after he was found to have submitted fake urine after his UFC 125
