The Celtics will be without 21-year old shooting guard Bill Walker for the next 6-8 weeks as he has had surgery to repair a torn meniscus in his right knee. He played in 29 games (0 starts) as a rookie last season for the Celtics and he averaged 7.4 minutes, 3.0 points, 1.0 rebound and 0.4 assists per game. The Celtics won’t miss Walker too much as he is likely #4 of #5 on the depth chart at shooting guard right now.
