One of the worst ref decisions in the last 10 years. Merab basically dominated him for the whole fight but got caught in a guillotine at the last 50 seconds of the third round. He didn't tap and survived the choke till the bell rang, but the ref decided that he was out after the fight ended.
Really Merab should be undefeated in the ufc because the judge robbed him in the Frankie fight while the ref robbed him in the ricky fight.
