An MRI on Bill Walker's right knee revealed a torn meniscus and he will miss six to eight weeks, meaning the Celtics would have to carry an injured Walker on their roster into the regular season. Walker left Wednesday's practice with a sore knee and returned to Boston for further examination.
Walker has had major surgery on both knees and has yet to reach his vast potential. He spent most of his rookie season in the NBDL. He played in 29 games last season.
