"It's part of those things you can't control. As soon as Kirk feels like he's able and healthy and there's not a high risk of re-injuring that where he's out a long time, he'll be back," Bulls coach Vinny Del Negro said on Monday night before Chicago took on the Bucks in Milwaukee.
Hinrich injured the thumb during practice Wednesday. He missed most of last season with torn ligaments in his right thumb.
"It's tough," Hinrich said Monday. "Last year was one of the hardest things I had to deal with. Ive never really been hurt for a long period of time before. It's tough because you work so hard in the offseason, preseason, and then whenever an injury happens it's very disappointing."
He was examined Monday by Bulls head team physician Dr. Brian Cole and hand specialists Dr. John Fernandez and Dr. Marc Cohen of Midwest Orthopedics at Rush University. Their examination confirmed the earlier diagnosis of a left thumb sprain.
"The guys are going to have to play a little bit extra minutes, probably. [We'll] use the bench as best we can," Del Negro said. "There's no easy answer to it."
