Starting shooting guard Rip Hamilton and backup point guard C.J. Watson are both doubtful for Monday's game against the Pistons at the United Center.

Hamilton injured his groin Dec. 30 against the Clippers in Los Angeles. He sat out the ensuing two games and returned Jan. 4 in Detroit where he re-aggravated the injury. He has sat out two games since.

Watson sprained his elbow during a 104-64 home win over the Grizzlies on Jan. 1 and has missed four games. Watson was seen running and doing some ball handling drills during Monday morning's shoot around.

Both players are considered day-to-day.

"The difficult thing with both he and Rip is we're not practicing--our team is not practicing," coach Tom Thibodeau said. "So you can't really see can they make it through a practice first. You have to wait to make sure that they're doing their rehab and they get out and try to stay on top of their conditioning whether it's in a pool, on a bike, whatever it is and then you're making those decisions."
