It's official: Fred Jackson is out

On Wednesday Buffalo Bills head coach Chan Gailey ruled out running back Fred Jackson (leg) for their game Sunday against the New York Jets. This is a huge loss, as Jackson accounted for about 40 percent of Buffalo's offense.

Jackson seemed optimistic after Sunday's loss to the Miami Dolphins, but Gailey was much more cautious. It turns out the leg injury is more serious than Jackson thought. Gailey said Wednesday that he wasn't sure when Jackson would return.

The Jets (5-5) and Bills (5-5) desperately need this game. The loser of Sunday’s game will fall way behind in the wild-card race.
