UFC light heavyweight Thiago Silva seemed to have his career headed in the right direction after picking up a submission finish of previously unbeaten Stanislav Nedkov less than two weeks ago at UFC on Fuel 6. However, it appears the talented Brazilian has been forced to do a U-Turn after the UFC revealed Silva was popped for marijuana metabolites after the bout.

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

As a result, Silva will be suspended for six months and see his victory changed to a No Contest meaning he has not officially notched a win since August 2009. He will not be fined but, similarly to heavyweight Dave Herman, the 30-year old will have to complete a drug rehabilitation program before receiving clearance to compete again.

The situation marks the second time Silva has been forced on the sidelines for illegal drug use, seeing a year of his career wasted after submitting an altered sample on the heels of a January 2011 fight and eventually admitting he’d used steroids leading up to the bout. Silva’s suspension for the offense ran out earlier this year.
