They don’t care that the Celtics had just 10 players for practice Wednesday. They don’t care that Paul Pierce  was home sick instead of gearing up for the rematch with the Lakers Thursday night at TD Garden. They don’t care that 38-year-old Shaquille O’Neal  is nursing a sore right Achilles tendon that has forced him to miss the last three games.
They don’t care that Semih Erden is about to miss his second straight game with a right adductor strain. They don’t care that the Celtics don’t have a proven replacement for Marquis Daniels , who went down with a bruised spinal cord on Sunday afternoon.
“You come to play the game,” Rivers said. “We don’t worry about the body count. They’re not going to worry about the body count, I can guarantee you that. We’ll be read. We’ll be fine.”
All the Lakers care about is getting revenge for that 109-96 Celtics win on Jan. 30 at Staples Center .
The Celtics were reduced to 10 healthy players in practice on Wednesday.
On the bright side, Delonte West  participated in his first full contact practice since his broken right wrist, suffered on Nov. 24 against New Jersey.
“We had 10,” Rivers said following Wednesday’s practice. “Paul’s is sick so he stayed at home. Semih is out, Shaq is out. Delonte practiced today but he won’t play [Thursday] or probably won’t play until after the break.”
Rivers said he does expect Pierce to play Thursday but not O’Neal or Erden. “I expect him to play,” Rivers said of Pierce. “He’s just not feeling good. We’ll see [Thursday]. I don’t expect Shaq, I don’t expect Semih. I don’t think [O’Neal] can go yet so we’re just going to wait until he gets healthy.”
Rivers said West was allowed to return but cautioned his players to try and use good judgment so that West’s right wrist wouldn’t be hit.
“We told [players] no reaching which is impossible with some of our guys but other than that, we got through it,” Rivers said.
