Celtics Allen doubtful to play on Sunday

Boston Celtics guard Ray Allen is traveling with the team to Atlanta for the start of their first round playoff series, but it is unclear if he will play in Game 1 on Sunday against the Hawks.

Allen has not played for the past two weeks because of a sore ankle.

Allen told ESPN.com that he is still day-to-day, but Celtics coach Doc Rivers said he is doubtful that Allen will play on Sunday.

"Honestly, I don't think he'll play, but we'll find that out," Rivers said. "He can play, so I'm not saying he's not, and it would be very nice if he does, but he's just not moving well and we'll just find out."

Allen, who is not practicing on Saturday, said swelling in the injured right ankle has gone down but there is still pain and that he will need surgery at some point.
