Bulls forward Carlos Boozer is still working back into game shape and the team is keeping an eye on his minutes.

"Every day I get a little more comfortable with the system," said Boozer, who made his season debut last week following a broken hand. "I'm getting in better shape by playing. It's exciting."

Chicago coach Tom Thibodeau used Taj Gibson in defensive situations against Houston in overtime.

"Carlos still has to — and we do as a team — have to work on our defense, particularly our pick-and-roll defense," Thibodeau said.

"(The Rockets) were running the high pick-and-roll and we were having problems with it. Taj had been doing pretty well defending it. I was also concerned a little about his minutes."
