The Celtics practiced on Tuesday for 75 minutes without the benefit of seven players.

Rajon Rondo (hamstring, feet), Shaquille O'Neal (calf), Glen Davis (illness), Nate Robinson (personal matter), Jermaine O'Neal (knee), Delonte West (wrist) and Kendrick Perkins (knee) were all absent from team drills.

Jermaine O'Neal, West and Perkins are out with long-term injuries, but Boston may be able to get the other players back for Wednesday night's game against Denver.

Celtics coach Doc Rivers said that Rondo is "iffy" for the game.

"I just leave it up to [trainer Ed Lacerte]," said Rivers. "[An extended break] may come at some point. I don't think it's a bad suggestion. It's been suggested already, I can tell you that. Eddie knows when it's close enough to play.

"The injury scares me. Both the foot and the hamstring. The foot is not the problem right now, but the hamstring can go from a pull to a tear. When you get the tear, you are talking two months so it's a tough little situation."
