Larry Bird is suffering from a recurrence of tendinitis in his Achilles tendons and surgery is a possibility - one that the Boston Celtics star would rather put off till the end of the NBA season.

"It's a matter of getting something done now or later," Bird said Wednesday prior to the Celtics meeting with the Chicago Bulls. "Mentally, I know I can't handle sitting out 20-25 games. I can't sit around the house watching someone else do my job."People are saying, `What's the difference if you are back by Jan. 1 or Jan. 15?' I'm not afraid of the knife. I know after the season I'm going to have it done. But I don't want to miss the games. I've never been out for a long period of time, and I just don't want to do it."

"We don't want to do anything unnecessary," said Celtics General Manager Jan Volk, " but there won't be any procrastination. We don't want to wait until February or March to make a decision."

Dr. Arnie Scheller, the Celtics' physician, said Bird aggravated the condition in games on consecutive nights against the New York Knicks and the Philadelphia 76ers last Friday and Saturday.

Scheller said Bird's therapy and medication were modified and his condition would be reassessed today.

"Some treatments we would consider would be an injection to relieve the swelling," he said.

He added that surgery is a possibility, but a decision on that is not likely for "the next two or three weeks."

The doctor confirmed earlier reports that if surgery is necessary Bird would be sidelined for 10-12 weeks.
