The Seattle Seahawks have built one imposing backfield.

The team agreed to a one-year deal with veteran running back Fred Jackson on Friday, according to multiple reports. The deal comes just days after he was surprisingly released by the Buffalo Bills.

Jackson, who signed with Buffalo as a free agent in 2006, is entering his 10th season in the NFL. He's a dual-threat back skilled at running between the tackles and catching the ball out the backfield.

He will join a Seahawks running-back corps that already includes Marshawn Lynch and the emerging Christine Michael.
