Tough news out of Boston, as Celtics center Jermaine O’Neal will have season-ending surgery on his ailing left wrist. The Celtics formally announced today that O’Neal has a chronic degenerative wrist condition which worsened after a fall during Boston’s game against the Dallas Mavericks on Feb. 20. No improvement was shown through immobilization and physical therapy, so the decision was made to proceed with surgery. The Boston Heraldhas the details: “The surgery will effectively end his season and likely his run with the Celts. O’Neal is in the final year of his contract with the team. Even before the development, the Celticswere in the market for a big man to help them in the stretch run of the season. O’Neal has played just 25 games this season, averaging 5.0 points per game and 5.4 rebounds. He played in 24 games last season, averaging 5.4 points and 3.7 rebounds.”
