It was starting to look familiar for Philadelphia on Monday, but the Sixers were able to hold off the Celtics down the stretch in a tight finish.
Philadelphia led 57-49 entering the fourth, but Boston tied it twice before going up 72-71 on Avery Bradley's 3-pointer, setting off a series of shots from beyond the arc.
Holiday answered with a 3 for the Sixers, then Ray Allen got the lead right back for the Celtics on a 3-pointer with 1:40 left. The Celtics had a chance to extend the lead after forcing the Sixers into a 24-second shot clock violation, but Rondo missed a shot and Iguodala got the rebound, leading to Turner's layup to put the Sixers up 76-75 with 40.4 seconds to go.
Rondo and Allen both missed shots that would have put Boston ahead, then Rondo fouled Turner with 14.4 seconds left as the shot clock was winding down.
The Celtics fouled Turner again with 12 seconds and he hit both free throws to extend the lead to 78-76.
