The Celtics want to win both games in Philadelphia so they can lead the Sixers' series decisively 3-1 when they return home.
The Celtics defeated the Sixers 114-102 on Friday night in Philadelphia to take a 2-1 series lead and recover home-court advantage.
But because aggressiveness is valued in this best-of-seven matchup between rivals, Robert Williams said on Saturday that "We expect to leave the game with more scars than yesterday."
The Time Lord sustained one of those wounds from a heavy fall as he extended a fourth-quarter possession by saving a long rebound.

Williams briefly left the field for the locker room, but the Celtics claimed he was ready to return when called upon.
Fortunately, his name is not listed on Boston's injury report as it gets ready for Game 4.
Marcus Smart's name is unfortunately on the list, which is bad news for the visitors.
