Celtics guard Marcus Smart will likely be out of the lineup until after the All-Star break, according to ESPN's Adrian Wojnarowski.
Smart suffered a left calf strain in Boston's loss to the Lakers on Jan. 30. He is now unlikely to return until the second half of the season begins on March 11, per Wojnarowski.
The seven-year veteran participated in on-court activities on Sunday before the Celtics faced the Pelicans in New Orleans. Boston has struggled since Smart's exit, losing six of 11 games while sporting the NBA's No. 18 net rating.
