Bulls guard Chris Duhon may be joining Eddy Curry and Loul Deng on the Chicago sideline with back spasms.

After only playing nine minutes in last nights victory over the Wizards, Duhon?s back bothered him so much that he was forced to take a seat on the bench.

"I can't stand straight up," Duhon said afterward. "We were in walk-through [at the shootaround] and I tried to stand straight up and I felt it tighten up and my back has stayed that way all day.

"I tried to go out there and see if I got in the flow if it would loosen up. But once I got subbed out and I had to sit down, it tightened back up."
