"He's fine," coach Doc Rivers said before the game. "Even by last night, he said he felt pretty good, and this morning he said he felt great. I told him, 'If I see anything, you're not playing or I'm taking you out.' "
Pierce, who's averaging a team-high 18.7 points, was not available before the game. He bruised his knee on a drive to the basket in Friday's loss to Atlanta and sat out the final few minutes of the third quarter. When he returned in the fourth, he was wearing a brace and had it taped.
Boston center Kendrick Perkins said Pierce appeared fine during pregame activities Saturday.
"He looked pretty healthy to me," Perkins said. "I saw him icing a lot throughout the day. He says he's ready to roll and I believe him.
"You know, Pierce is a warrior. He don't miss very many games to injury. He's not one of those guys that just has a sore quad and decides to sit out or something crazy. He's a warrior and he leads by example."
