HOUSTON — Houston Rockets guard Tracy McGrady says he'll miss three weeks to rehabilitate his sore left knee.

McGrady has missed Houston's last three games after starting the first 15. He had arthroscopic surgery in May, and admitted he came back a little bit too soon.

McGrady is Houston's second-leading scorer, averaging 15.6 points this season.

McGrady visited with orthopedist James Andrews on Monday. The team said Andrews confirmed the initial medical assessment by team doctor Tom Clanton that McGrady is suffering from general soreness in the knee.
