James has served two stints with the Bulls this season, most recently signing a 10-day contract in the wake of Derrick Rose's back injury.

His best game came in a Feb. 18 loss to the New Jersey Nets when he had 16 points and seven assists. Thibodeau did not rule out the possibility of James returning to the Bulls later this season.

"There's always that chance," Thibodeau said. "I think the one thing he did a great job for us in both stints. The one thing: Mike stays ready. You can count on that part and then if there's the need, we wouldn't hesitate to bring him back."

Thibodeau says he expects to return to his normal point guard rotation with C.J. Watson backing up Derrick Rose. Watson has missed the last two games with post-concussion symptoms.
