Cleveland Cavaliers rookie Kevin Porter Jr. is expected to miss two weeks because of a sprained left knee, the team announced Monday.

Porter suffered the injury in Sunday night's loss to the Minnesota Timberwolves. His knee buckled awkwardly in the third quarter when he tried to change directions, and he had to be helped to the locker room.

The Cavaliers said that Porter will be reevaluated in about two weeks.

Porter, the 30th overall pick in the draft, is averaging 8.5 points and 3.3 rebounds per game this season.
