Boston's Marcus Smart (leg) out vs. Nets, Hawks

Boston Celtics point guard Marcus Smart will not travel on the team's upcoming two-game road trip because of what the team termed a "lower left leg" injury.

Smart appeared to bang knees with Brooklyn's Thomas Robinson trying to defend in transition with 9:26 to play in the fourth quarter of Friday's win. The team initially said Smart suffered a left knee bruise and would miss the rest of the game. Celtics coach Brad Stevens said Smart would have an MRI to further evaluate the injury.

The team said Saturday that Smart will not travel for games in Brooklyn (Sunday) and Atlanta (Tuesday). Boston is back home on Wednesday night to play host to Philadelphia.

Smart's teammate Jae Crowder downplayed the injury after Friday's game while noting, "[Smart is] a little sore. ... I think he’ll be fine though. It’s precautionary reasons he’s gonna get checked out [Friday night] and it sounds like he’ll be OK."

Evan Turner also had a medical evaluation, and the team said Saturday that he has a right leg strain, but would travel and be available for both games.

The Celtics recalled rookie guard Terry Rozier and second-year swingman James Young from the Maine Red Claws of the NBA Development League to add depth for the trip.

Smart missed three games this month with a toe injury. The Celtics had played some of their best basketball while back at full strength, but will have to endure without Smart again for at least the next two games.
