Jackson, 34, is entering his ninth season with the Bills and is the team’s captain. He missed two games last season with a groin injury after playing all 16 games in 2013.
Jackson saw the most action of any Buffalo running back last season, rushing for 525 yards and two touchdowns on 141 carries. He figures to play a different role now that the Bills have added Pro Bowler LeSean McCoy.
Jackson also led the Bills with 66 receptions last season and was third on the team with 501 receiving yards. McCoy is also a capable receiver out of the backfield.
