UFC featherweight Robbie Peralta suspended six months for positive marijuana metabolites

Robbie Peralta has some serious "Problems" now.

The featherweight knockout artist has received a six months suspension after failing a UFC on Fuel TV 9 post-fight drug test.

UFC confirmed (via MMA Fighting) that Peralta had been flagged for marijuana metabolites and that he had agreed to attend drug rehabilitation classes. Just like fellow combatants Dave Herman and Thiago Silva, Peralta must pass a drug test upon completion of the suspension in order to be reinstated to the active roster.

Peralta(16-4 1 NC) faced Akira Corassani on the opening fight of the Fuel TV main card upset via unanimous decision by the surprisingly aggressive Swedish veteran of The Ultimate Fighter (TUF) season 14, snapping his unbeaten streak at 10.

The suspension is retroactive to the date of the fight, making him eligible to compete on Oct. 6 as long as he can lay off the reefer.

The UFC on Fuel TV 9 event was held in Stockholm, and was sanctioned by the Swedish Mixed Martial Arts Federation. All 26 fighters on the card were tested according to UFC.

Will Peralta bounce back?
