Check out this video interview with Fabricio Werdum (pygmy savage language only, sorry) where he claims he let go of the armbar that won him Saturday’s fight against Big Nog when he heard a pop and the Nogster screamed. According to Werdum, this was before Mario Yamasaki stepped in to stop things, which makes it lucky for him that Yamasaki took the scream as a verbal submission and actually stopped the fight.
