CLEVELAND (AP) -- Cavaliers rookie guard Dion Waiters will miss at least one week with a sore left knee and may need surgery.
The Cavs said an MRI taken Tuesday revealed a loose fragment in Waiters' left knee. He injured his knee in the first half of Monday's home loss to Indiana and did not return.
He will rest and have treatment over the next week, and the Cavs said it's possible the No. 4 overall pick in last year's draft may need an arthroscopic procedure.
The loss of Waiters is another blow to the Cavs, who are already missing All-Star guard Kyrie Irving and forward Anderson Varejao with injuries.
On Wednesday, the Cavs host the Miami Heat, who will attempt to extend their winning streak to 24.
