Bulls head coach Billy Donovan said Monday that Ball (knee) is doing well following his surgery, Julia Poe of the Chicago Tribune reports.

Ball underwent surgery last Wednesday and is still on crutches, but Donovan said the team feels optimistic about the procedure. Per Poe, Ball will need more time to recover before the medical staff can clear him to begin rehab, but the Bulls are still giving the guard a chance to return this season.
