CHICAGO: Kyrie Irving has a hyperextended right knee and won't play tonight when the Cavaliers face the Chicago Bulls. He is listed as day to day moving forward and is questionable for tomorrow's home game against the Toronto Raptors.

Irving banged knees with teammates in practice before departing on this three-game road trip. He tried playing through it during the two games in Florida, but didn't look like himself and shot 10 of 29 in the two games. He said after the Miami game the knee was affecting his game, so the medical staff decided to shut him down. Shaun Livingston will start tonight at point guard.

Despite being shut down for a few days, coach Byron Scott said he's not real concerned about the injury.

"It's one of those things that needs rest," Scott said at this morning's shootaround. "The last couple of games, I think it's built up. He hasn't been able to have any rest on it, so when you have a knee that's as sore as his is, you need rest and he needs treatment."

Irving has yet to face Bulls star Derrick Rose, and that streak will obviously continue since both players are expected to miss tonight's game. Rose is getting closer, but still hasn't returned to the court since his knee injury in last year's playoffs. 

The Bulls will also be without Taj Gibson (sprained left knee) and Kirk Hinrich (right elbow) is questionable. Hinrich participated in this morning's shootaround, according to the Chicago Tribune, and will be a game time decision.
