Bulls head coach Tom Thibodeau confirmed Saturday that veteran reserve guard Kirk Hinrich has a concussion, which came as a result of a head injury suffered in the fourth quarter of Friday evening's win over Indiana at the United Center.
Following Saturday afternoon's practice at the Berto Center, which Hinrich didn't participate in, Thibodeau said that the floor general would be out of the lineup for "probably a couple days," while going through a series of tests, per NBA protocol for concussions.
"He said he was feeling a lot better today," the coach said, before adding, "I don't want to get ahead of myself."

Hinrich was unavailable for comment after the Bulls' victory over the Pacers. His head crashed into Bulls rookie Erik Murphy, then the court itself and he appeared dazed afterwards, before being subbed out of the game and subsequently heading to the locker room.
Meanwhile, All-Star center Joakim Noah, who will be shut down for a week, continues to recover from the soreness resulting from his lingering strained-groin injury, which occurred during a practice in the first week of the Bulls' training camp.
"We want him locked into the rehab, but we want to be patient. We want to make sure he's completely healed before we move forward with on the floor stuff and contact. He's working the entire practice and coming in two or three times a day. This next week is about him rehabbing," Thibodeau said. "Obviously, you'd like him out there. But we're going to pull back on that right now."

Starting shooting guard Jimmy Butler, who missed the last two games with a bruised left knee suffered in last Saturday's Bulls win in Brazil, could return for Monday night's home game against Milwaukee, according to Thibodeau.
"I want to see where he is tomorrow. We didn't have contact today in practice. I want to see where he is taking some contact," the coach said. "He didn't do all of [Saturday's practice]. He did a lot of the shooting."
Butler said his knee is improving, but was also unsure about playing against the Bucks.
"Moving a little bit, just getting shots up, trying to cut and get my pace up," he said. "I don't know [about playing Monday]. Just have to have Sunday, then we have Monday. So we'll see how it feels tomorrow, tonight and we'll go from there."
The Bulls have yet to field their entire starting lineup in a game this preseason, but are undefeated, with a 5-0 record in the exhibition games.
