Muscle Shark tests positive for steroids

UFC lightweight champ

Sean Sherk

tested positive for the substance Nandrolone Metabolite following his successful title defense earlier this month, according to the California State Athletic Commission. His opponent, Hermes Franca, also flunked the post-bout drug screen, testing positive for Drostonalone. Both have been

fined $2,500 and suspended for one year

by the CSAC. It's likely that Sherk will also be stripped of his title by the UFC. That's what happened to heavyweight Tim Sylvia after he tested positive for steroids following a 2003 fight.
