Paul Pierce took a hard foul from Joe Johnson at the 10:38 mark and got up holding his lower back. Kendrick Perkins, who was called out by Mike Bibby before the game, got into it with several Hawks players and had to be restrained.
After looking uncomfortable at the foul line, Pierce has asked out of the game. He was replaced by James Posey.
Bibby is being booed every time he touches the ball.
