ortiz was dirty headbutting hard by jumping towards floyd following with a punch which could of injured him easily. mayweather retaliated similarly, making it look like accepting the apology and the knockout. neither did right but the retaliation was justified in some ways. regardless, floyd was ahead and winning on the scorecards. ortiz missed alot those punches when he had him against the ropes. i dont know why vic did that cause it was too early, probably just got frustrated and went for the headbutt, just a strange ending.
