Rather he wanted or not. Foreman had no choice but to fight on. He's fighting on HBO in new Yankee stadium against a fighter looking to win his 3rd title in a different weight class. Not only that but he's getting way more coverage than he really deserves cuz he's a Jew studying to be a rabbi. Factor that in with the fact that he can't punch for shiit and has already had 2 previous fights undeservedly go his way already. The boy had more cons than pros. Him quitting after going down without getting hit or slipping on a logo would of been pretty fucking bad for him. It would of made him a bigger laughing stock than Audley Harrison. And that's pretty big. The fact that he would need surgery wouldn't even matter. The damage would of already been done. I have no doubt Foreman was well aware what the outcome would be if he quit or fought on. The two options running through his head were quit and your a joke. No one will ever take you seriously. Or fight on till it gets stopped (fuck you Mercante I know was what he was thinking) and pray to whoever the hell prays to that Cotto don't hurt him. He did the smart thing rather he wanted to or not.
