Cavaliers center Tyler Zeller currently still does not have a timetable for his return from his recent appendectomy, the Cleveland Plain Dealer reports Monday. He remains out indefinitely.

Zeller is not sure if he will be ready when the lights come on to begin the regular season, either. He had the surgery last Friday.

Zeller is expected to fill a backup role behind Anderson Varejao this year for Cleveland. He would also be behind Andrew Bynum, whenever he is ready to play.
