It's official: Fred Jackson out Thursday

As expected, Buffalo Bills head coach Chan Gailey confirmed Monday that starting running back Fred Jackson will not play in Thursday’s game against the Miami Dolphins.

Jackson suffered a concussion on the final drive of Sunday's loss to the New England Patriots. Considering it was a head injury and Buffalo (3-6) has a quick turnaround, it seemed unlikely Jackson could recover. Gailey made it official Monday afternoon that Jackson will skip Buffalo's next game.

I'm not sure if this is good news or bad news for Miami (4-5). Yes, Buffalo's starting running back is out. But that means Miami must now stop dynamic backup C.J. Spiller, who is leading the NFL with 7.3 yards per carry.

Spiller wasn’t getting enough carries this year in large part due to Jackson. Expect Spiller to get a healthy workload Thursday against Miami.
