Mike D'Antoni says he is optimistic that Stoudemire will be available for Game 3 on Friday and less optimistic that Billups will play.

Stoudemire was scheduled to receive treatment for a back injury Thursday afternoon in his Manhattan apartment. The Knicks advised the All-Star power forward to remain home rather than take the two-hour round trip drive to the team's practice facility in Westchester.

Stoudemire, according to sources, informed the Knicks coaching staff on Wednesday that he will play against the Celtics on Friday.
