Chauncey Billups is "praying for a miracle" that he will be healthy enough to play again in New York's first round series against the Celtics, but is not optimistic about Game 4 on Sunday.

Billups had blood drained from his knee on Thursday and has not been able to run since leaving Game 1 in the final minute.

Game 7 would be played a week from Sunday, but the Knicks are down 0-3.

Asked if that would be enough time for him to return, Billups said, "I think it's maybe a chance. But I don't know that to be 100% true. I'll just go day to day and hopefully the cortisone hasn't kicked in yet. But that's just me. I'm praying for a miracle."
