Khan had a couple good scoring rounds but I think he got rattled with those body shots in the 4th. I couldn't understand why he kept shaking out his right hand. Even with a few good punches he could gain any respect from Crawford. Crawford wasn't in his wider stance that he usually carries with a lot of weight on that front foot. You could tell he was looking for a big shot. I didn't see if it was Khan who quit or the corner, very disappointing to see a fighter quit. It was definitely a low blow in particular just by Khan's immediate reaction, I don't think he faked it. If that was a legitimate shot, as Crawford claims, I think Khan would have displayed immediate pain much different, but then again it didn't seem to be that severe either.
