Watch: McRoberts gets flagrant for vicious hack on Biyombo

Bismack Biyombo has been a colossal thorn in the Miami Heat's side in Sunday's Game 7, and Miami's frustration started to show late in the game.

After Biyombo got away with what looked like a blatant loose-ball foul on Heat forward Josh McRoberts to secure an offensive rebound, McRoberts responded by bringing a violent fist down on Biyombo as he drove to the basket, resulting in a flagrant-one foul.
