Based on that timetable, Jack will miss the remainder of the Cavaliers preseason schedule but will be available for the regular season. Cleveland will have six games over those 10 days.
Jack will be back on the court when the Cleveland Cavaliers kick off their regular season at home against the Brooklyn Nets. He and Irving will pose as one of the NBA's best backcourts, similar to what Jack formed with Stephen Curry formed in Golden State.
