The incident occurred with 3:48 remaining in the fourth quarter and the Celtics holding an 89-87 lead. Rondo fell while guarding a driving Jeff Teague, who cut left and passed to DeMarre Carroll. Teague never made contact with Rondo, who fell backward at the foul line.

The Hawks rallied for a 105-97 victory.
