WALTHAM, Mass. – Second-year guard Marcus Smart remains sidelined with a left big toe injury, but is hopeful he can return in time for Friday’s game against the Atlanta Hawks.

Smart went through some of the team’s practice on Monday prior to them departing for Milwaukee for Tuesday night’s matchup against the Bucks.

“Today was more of checking to see where I was,” Smart said. “It felt good. But like I said, they want to make sure … give me another day, few days to rest.”

There’s still a bit of mystery surrounding the sprained ligament injury in Smart’s left big toe, one that he and the Celtics are not sure about when it occurred.

If Smart misses Tuesday’s game against Milwaukee and Wednesday’s matchup against Indiana, it will make four straight games he has missed with this injury.

“This is extremely tough,” Smart acknowledged. “Everybody wants to play. When that shot is taken away from you, you definitely feel a certain way about it. But that’s part of the game; injuries. Let these guys do their job and try to help me get better.”

Smart has appeared in three games (all starts) this season, averaging 12.0 points, 3.7 assists and 2.3 rebounds along with 2.3 steals which ranks fourth in the NBA this season.
