Jae Crowder has ACL sprain, won't need surgery

The Celtics announced Monday that forward Jae Crowder sprained his left ACL during Sunday's season-ending Game 4 loss to the Cavaliers.

Crowder was injured Sunday when J.R. Smith delivered a backhand strike to his face while the pair jockeyed for a rebound.

Crowder's injury is not expected to require surgery.
