After being plagued by injuries throughout the season, the 76ers continue to have problems in the off-season.

Today, reserve guard Speedy Claxton will undergo arthroscopic surgery on his left shoulder to repair an injury suffered at the end of the regular season, the Sixers announced yesterday. Also, reserve Raja Bell sprained a ligament in his left thumb during a recent workout and will wear a cast for the next three weeks.

Surgeon Craig Morgan will repair the torn left labrum in Claxton's shoulder today at Wilmington Hospital in Delaware. The recovery time will be determined after the surgery, according to the Sixers.

This is the second time since the Sixers picked Claxton in the first round of the 2000 draft that he has had to have surgery. After tearing his left anterior cruciate ligament during the 2000-01 preseason, Claxton missed the season and, therefore, was classified as a rookie this season.
