finally got round to watching it last night. don't know what it is with IBF refs but that was another shocking performance. should have stamped his authority straight away and should have perhaps even disqualified them. Everything stemmed from the headbutt in the 1st round - which was accidental in my view then they just started fouling each other right through the fight with Lazarte even resorting to biting. the riot afterwards was a disgrace and a member of Casimero's corner got a proper kicking. It certainly sounded like a football crowd in the arena that night and we all know what Argentine hooligans are like.
