Celtics’ Smart out 2-3 weeks with torn left calf muscle

BOSTON (AP) — Boston Celtics guard Marcus Smart is expected to be sidelined two to three weeks because of a torn left calf muscle. The team said Sunday that an MRI revealed the Grade 1 tear. Smart missed the final 10:28 of Boston’s 96-95 loss to the Los Angeles Lakers on Saturday night after he was helped off the court following a collision with Montrezl Harrell underneath the basket. Harrell tipped in a missed layup and stepped on Smart’s foot as he came down.
