Buffalo Sabres coach Lindy Ruff is still in severe pain, and it's unclear when he'll be able to resume coaching, a day after breaking three ribs during an on-ice collision with defenseman Jordan Leopold. General manager Darcy Regier on Tuesday officially listed Ruff as day to day, but said it's unclear when the coach will be able to run practice or return behind the bench. Ruff stayed at home Tuesday after getting about four hours of sleep, Regier said after having a conversation with the coach.
