Ravens' starting cornerback Chris McAlister says the team has told him he will be sidelined three weeks due to a knee strain. McAlister says he's been bothered by the knee for weeks but played though the injury. McAlister is still hoping to return after the bye week in time for the game against the Pittsburgh Steelers on Nov. 5th. McAlister's injury was revealed Monday when the team announced he was day-to-day.
