Derrick Rose revealed Sunday that his hamstrings are "on fire" after workouts and drills as he rehabilitates a torn ACL in his left knee.

Rose has been adamant he will not return to the Chicago Bulls until he is fully healthy and completely comfortable mentally.

Rose went through his usual pregame routine before Sunday's game against the Los Angeles Lakers, shooting around and doing cardio drills.

"We'll cross that bridge when we get there," Tom Thibodeau said before the game. "For us right now the guys that are playing have to concentrate on their improvement and our next opponent. Derrick has to concentrate on his rehab. And until that changes that's the way it has to be and that's the way we're approaching it."
