Already without their top two players, the Cavaliers have now lost a third to injury.

Dion Waiters will miss at least a week after an MRI on Tuesday revealed loose cartilage in his sore left knee, the Cavaliers announced.

He will be re-evaluated after rest and treatment for a week, with potential for arthroscopic surgery

The Cavaliers already are without All-Star point guard Kyrie Irving for at least another 2-3 weeks as he recovers from a sprained left shoulder. They lost Anderson Varejao for the season when they discovered a blood clot after surgery for a quad injury in January.
