Andre Dirrell, a super middleweight boxer, won his fight on Saturday after his opponent, Venezuelan boxer Jose Uzcategui, was disqualified for hitting him after the bell.  

Uzcategui apologized after the fight, and everything seemed to be okay, but then Dirrell's uncle walked up and sucker-punched him hard! Now it looks like the uncle might be facing assault charges.

Check out the slow-motion video of the incident below!
