I just w2atched a little video of Haye showing off his broken hand. Now, I once saw Calzaghes broken hand after a fight, maybe against Bika i can't remember, but it was almost twice the size and discoloured. I'm quite confident that Haye has not broken anything atall, especially nothing that the little piece of wrap tape is going to help anyways.
