Notes: Chicago's Allen OK after scary fall

Chicago Bulls forward Malik Allen is listed as day to day after spraining his neck against Minnesota and being carted off the court on Tuesday night.

Guard Chris Duhon is also day to day with a bruised jaw after taking a shot to the face during Tuesday's game against the Timberwolves. Chicago hosts Cleveland tonight.

Allen was injured 20 seconds into the second quarter, rotating to defend Rashad McCants on a drive. As he fell backward, Allen's head banged into teammate Darius Songaila's shin.

Allen's neck was immobilized, and as he left the court he moved his arms and raised a fist. He was taken to Rush University Medical Center, where he underwent a CT scan, MRI and neurological exam before being released.

In other Bulls news, Tim Thomas was waived, clearing the way for the forward to possibly sign with a playoff contender.
