Boston Celtics guard Marcus Smart will miss a couple of weeks after a left ankle sprain suffered during Wednesday night's 121-96 loss to the New York Knicks, according to a league source.

Smart suffered the injury by landing on Justin Holiday‘s foot with 48 seconds to go in the first half. He limped out of the court with the help of teammates Avery Bradley and Jae Crowder.
