Watch below, as the uncle of Andre Dirrell sucker punches his opponent, following their bout last weekend.

Dirrell won the super middleweight world title on a controversial eighth-round disqualification, after Jose Uzcategui drilled him with a three-punch combination, the final punch landing while the bell was still ringing to end the round.

Dirrell's trainer, and uncle, Leon Lawson, Jr., then landed three punches on Uzcategui after the fight, which got him suspended indefinitely by the World Boxing Council.
