NEW YORK (AP) -- The New York Knicks say center Tyson Chandler is day to day after an MRI exam of his left knee revealed a bone bruise.

Chandler was hurt Wednesday night in the opening minute of the Knicks' exhibition victory over the Brooklyn Nets when he banged knees in a collision with Gerald Wallace. He was able to walk to the locker room on his own but left the arena on crutches. He said after the game he didn't have much concern about the injury.

The Knicks open their season Nov. 1 at Brooklyn. They are already dealing with injuries in their frontcourt to Amare Stoudemire and Marcus Camby, and Rasheed Wallace still hasn't played while trying to work his way into shape after a two-year retirement.
