Ben Gordon gave Chicago the lead 15 seconds into the second overtime. The Celtics missed shots on their first three possessions, then failed to get a shot after Rajon Rondo controlled a rebound, the Bulls' John Salmons providing a 114-110 advantage with 2:36 to play. Glen Davis missed underneath out of a timeout, then Gordon missed a jumper.
Davis dunked off an Eddie House feed to cut the Celtic deficit to 2. But Joakim Noah dunked with 1:26 remaining, blocked a Ray Allen drive, then rebounded a Paul Pierce miss and made a free throw for a 117-112 lead with 35 seconds remaining.
Pierce cut the deficit to 2 with a third-chance 3-point play with 27.3 seconds left.
