Washington ? Gilbert Arenas had a third operation on his bothersome left knee Wednesday morning, once again throwing into doubt his status for an upcoming Washington Wizards season.

Arenas had a “moderate amount of debris” removed from the knee after experiencing swelling and discomfort during his rehabilitation. The Wizards offered no timetable for his return – beyond the fact that he obviously won’t be ready for the start of training camp next week – but Arenas told The Washington Post that he plans to be back on the court in early December, which would rule him out for the first month of the season.
