In the sport of boxing, there is a viciousness there that isn’t apparent in other sports. Many boxers are naturally tough guys, and many do not come from the best neighborhoods. In a sport that simulates combat in a sport environment, animosity and intention to do harm to the opponent is quite common. This is especially apparent in sparring when boxers from other gyms visit.
In the Andre Dirrell vs. Jose Uzcategui match, Dirrell is knocked out from an additional strike after the bell, resulting in the DQ of Uzcategui. Not surprisingly, his uncle became incensed over this, but nobody expected him to sucker punch the dude.
