The Indiana Pacers appear to have a set playing rotation and a set roster of 12. Coach Rick Carlisle, however, doesn't recommend any assumptions.

"I wouldn't rule out the possibility of a change, but I'm not sure how likely a change is," he said before Monday's game with Chicago at Conseco Fieldhouse.

Jamison Brewer, Primoz Brezec and rookie James Jones have been on the injured list most of the season, although all three have played.

Carlisle said he wouldn't be reluctant to activate any of them, whether by injury or by choice. Jermaine O'Neal was injured in Monday's game, but is not expected to be out for an extended period.

Pacers forward Ron Artest knows what he would do: Activate Brewer. Artest occasionally slips in a plug for the point guard, and did it again Monday.

"Hopefully we can get Jamison Brewer off (the injured list) and he can help us keep these point guards contained," Artest said. "He can be the fourth point guard or whatever. Any minutes we get from him would be helpful for us."
