Thiago Silva suspended six months by UFC for failing drug test

UFC light heavyweight fighter Thiago Silva has been suspended six months and will undergo a drug rehab program for testing positive for marijuana after a post-fight drug screen on Nov. 10 in Macau for UFC on FUEL TV 6, according to a report Thursday from John Morgan of USA Today Sports. 

The UFC issued a statement saying Silva admitted to using drugs and said he will have to take another drug test in six months in order to compete again:

"The UFC organization has a strict, consistent policy against the use of any illegal and/or performance-enhancing drugs, stimulants or masking agents. [S]ilva 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."

This isn't the first time Silva was suspended for a drug test; in January 2011, after beating Brandon Vera at UFC-125, Silva was suspended and fined by the Nevada State Athletic Commission because he submitted a fake urine sample.

The news was also reported by MMA reporter Ariel Helwani.
