All I see is a blatant Hopkins headbutt. Bet he doesn't land that shot without first landing that intentional headbutt.
You're right. Calslappy shouldnt be able to slap with the inside of his glove he couldve cut Bernard up with the laces of his gloves just like he did so many other fighters in the past that dirty ****.
I'm not even a calzaghe fan, but a headbutt and the level of dirty tactics Hops uses and what you mentioned from calzaghe are not even comparable.
