The Chicago Bulls' Kirk Hinrich is questionable for Game 5 against the Brooklyn Nets with a bruised calf after scoring 18 points and dishing out 14 assists in almost 60 minutes in Saturday's triple-overtime Game 4 victory.

Hinrich's injury was determined by postgame tests after Saturday's victory, which gave the Bulls a 3-1 series lead.

Joakim Noah, who was supposed to only play about 30 minutes in Game 4, ended up playing almost 40 but coach Tom Thibodeau sounds optimistic about his center's chances to contribute on Monday night in Game 5.

"[Hinrich] got banged up a little bit," Thibodeau said. "Jo I think is OK. So health-wise we're relatively good."

Thibodeau was hesitant to say whether Hinrich would miss any time.

"I don't want to jump to any conclusions," he said. "We'll see where he is [Monday]."

Thibodeau believes Noah, who continues to battle plantar fasciitis in his foot, is feeling better.

"He says he's feeling a lot better," Thibodeau said. "The big thing was from the end of the regular season where he would play and the next day he would be extremely sore. Now he's at the point where he's playing and he doesn't have that same soreness the next day. So that's a big plus for us and he's starting to get his timing back."

If Hinrich is unable to play, look for Thibodeau to insert veteran guard Nate Robinson into the lineup. Robinson had an epic Game 4 performance by scoring 34 points, including 23 in the fourth quarter.
