Saints running back Deuce McAllister will miss the rest of the NFL season after tearing a knee ligament. McAllister said an MRI exam Tuesday confirmed his worst fears: He tore his left anterior cruciate ligament in Monday night's 31-14 loss to Tennessee. "I didn't want to believe, but just taking that walk to the locker room you could feel it just kind of giving way a little bit," he said. 'And that was just kind of reminiscent of how the other one felt," he added, referring to a 2005 injury.
