Robbie Peralta has been suspended six months after failing a UFC on FUEL 9 post-fight drug test.
In a statement, the UFC confirmed that Peralta had been flagged for marijuana metabolites.
The promotion said that the featherweight has agreed to attend drug rehabilitation classes and must pass a drug test upon completion of the suspension in order to be reinstated on to the active roster.
Peralta faced Akira Corassani on the opening fight of the FUEL broadcast as a lopsided favorite, but was upset in a unanimous decision, snapping his unbeaten streak at 10. Prior to that, he'd held UFC wins over Mike Lullo and Jason Young.
The 27-year-old Californian has a career record of 16-4 with 1 no contest.
The suspension is retroactive to the date of the fight, making him eligible to compete on Oct. 6, pending a passed drug test.
The April 6 event was held in Stockholm, and was sanctioned by the Swedish Mixed Martial Arts Federation. According to the UFC, all 26 fighters on the card were tested.
