DEERFIELD, Ill. -- Chicago Bulls guard Kirk Hinrich is day to day after straining his right groin during Tuesday night's game against the Oklahoma City Thunder.

Hinrich, who sat out the second half of the Bulls' win, did some light shooting with his teammates after they watched film Wednesday. Bulls coach Tom Thibodeau said it was just a "tweak."

"He should be OK," Thibodeau said. "Just tweaked it, so we'll see. He said he felt better."

The 31-year-old Hinrich already sat out one game this preseason because of a thumb injury. Hinrich, who was signed as a free agent this summer, has missed 28 games the past two seasons because of various injuries.

Thibodeau said Hinrich will be a game-time decision for Friday's preseason finale against the Indiana Pacers in South Bend. He also said the veteran guard did not have an MRI, though he didn't exactly rule out the possibility that Hinrich would be sidelined for the regular season opener next Wednesday.

"I'm thinking about (Thursday)," Thibodeau said. "He's better today than he was. We'll see where he is (Thursday)."

Bulls guard Rip Hamilton dealt with a groin injury of his own last season and he knows it can be tough to recover from.

"It's tough," Hamilton said. "Because you want to be careful with it. A groin can last you (a while). It can linger. You just want to jump on it as quick as possible, and the one thing that was good with (Hinrich) was he didn't come back and play the second half. Sometimes your adrenaline will allow you to say, 'Nah, I don't want to sit down, I'll figure it out at the end of the game,' and that's what most players do and I think (the trainers) did a great job of really jumping on it early and saying, 'All right, shut him down and let's jump on it and hopefully get him right, right now.'"
