BOSTON -- Chicago Bulls head coach Fred Hoiberg admits there is a "sense of relief" within the organization that Michael Carter-Williams' left knee injury isn't more serious. Carter-Williams, who is expected to be out four to six weeks, injured the knee during Monday night's win over the Brooklyn Nets.

An MRI on Tuesday revealed that he had no ligament damage, just a bone bruise and a sprained left wrist.

"First and foremost there was a sense of relief that it wasn't more serious than that," Hoiberg said after Wednesday's shootaround. "Obviously when he went down he had a lot of pain. We're thankful that he will be back in uniform this season. He's brought us an element that we lacked with that second group. He's picking up full court, he does a great job getting into the paint, making the right play. So we'll miss him."

The Bulls played the Boston Celtics on Wednesday night.

"We got to have all our guys ready," Hoiberg said. "Paul Zipser is going to have to keep himself ready based on certain matchups. I thought he gave us good minutes in the preseason. Denzel obviously will have to be ready and give us some minutes. And then Jerian Grant, after being inactive for the first three games, there's a chance he'll get a shot as well. A lot of it will be based on matchups, but all three of those guys will have to be ready."

Bulls small forward Doug McDermott did not play against the Celtics. McDermott entered the league's concussion protocol after taking a few hard shots in Monday's game.
