The procedure will be completed at Cleveland Clinic Sports Health, after which an official timetable for an expected recovery will be provided, but Shumpert could miss six to eight weeks, league sources told ESPN's Adrian Wojnarowski.
Shumpert, who has missed four out of the Cavs' past five games because of his left knee effusion (commonly known as a fluid buildup), was re-evaluated Tuesday by Cleveland team physicians Dr. Richard Parker and Dr. James Rosneck. It was determined at that time that surgery was necessary.
Cavs guard Dwyane Wade offered some words of encouragement to Shumpert after Thursday's game.
Shumpert is averaging 4.8 points, 3.1 rebounds and 1.3 assists while shooting 38.6 percent from the field in 20.8 minutes per game this season. He has started six games at point guard because of injuries to Derrick Rose and Isaiah Thomas.
