Marcus Smart, injured Saturday night in a loss to the Lakers, has a tear in his left calf muscle.

Boston blows a fourth-quarter lead, and a last-minute comeback falls short in a 96-95 defeat.

The league reschedules three February games for the Celtics, who are among the teams with the most games postponed so far this season.

The Celtics’ projected starting five of Kemba Walker, Jayson Tatum, Jaylen Brown, Marcus Smart and Daniel Theis played together for the first time this season.

Jayson Tatum, who missed five games while in virus protocol, emerges to propel the Celtics to a 119-103 victory in Chicago.

Jaylen Brown scores 33 points despite playing only 19 minutes, and Boston rolls to a 141-103 win over Cleveland.

Smart expresses his frustration after Embiid shoots more free throws (21) that the entire Boston team (20) in Philadelphia’s victory Wednesday night.

Joel Embiid also adds 10 rebounds as Philadelphia prevails at home.

Williams is expected to return to action on Wednesday after ‘some rough days.’

Kemba Walker plays for the first time this season in Boston’s blowout loss to New York.
