BOSTON (CBS) — An Achilles strain will keep Marcus Smart out of Boston’s Monday night tilt against the Philadelphia 76ers.

Celtics head coach Brad Stevens said Smart will not travel to Philadelphia for Monday’s game and will instead stay back in Boston to rehab a left Achilles strain he suffered in Friday night’s loss to the New York Knicks. Stevens said there is a chance Smart could play Wednesday night when the Celtics host the Orlando Magic at the TD Garden.
