Pregame: Pierce to play vs. Pistons

BOSTON -- Boston Celtics captain Paul Pierce, who missed Monday's game in Minnesota due to personal reasons, is back in the starting lineup for Wednesday's visit from the Detroit Pistons.

Celtics coach Doc Rivers wouldn't elaborate on Pierce's absence other than to reiterate that it was for a personal matter. He had said previously it wasn't for any negative issue, including a sore right ankle that he iced in the fourth quarter of Sunday's loss to the New York Knicks.

Boston will stay big with its starting lineup, running Pierce alongside Avery Bradley, Jeff Green, Brandon Bass, and Chris Wilcox.

Rivers didn't have much of an update on Kevin Garnett, who is in the midst of a two-week break to allow left ankle inflammation to subside.

"Honestly, I haven’t asked one question about [Garnett's return]," said Rivers. "I don’t even know when two weeks is. Whenever it is, it’s probably coming up, and he’ll play."

Rivers said he wasn't overly worried about Garnett shaking the rust from his absence.

"We have a lot of practice days coming up and Kevin's been working out," said Rivers. "He hasn’t lost all his conditioning, but you do lose some when you don’t play."
