JACKSONVILLE, Fla. (AP) With Maurice Jones-Drew out, the Jacksonville Jaguars have signed running back Keith Toston and waived rookie defensive end Ryan Davis.
Toston will back up Rashad Jennings, who will start Sunday's game at Green Bay in place of Jones-Drew.
Jones-Drew sprained his left foot in Sunday's loss at Oakland and could miss several games.
Toston spent the preseason with the Jaguars before being waived in final cuts. He ran 22 times for 171 yards, including a 42-yard touchdown at New Orleans. Toston spent the 2010 season and the 2011 preseason with St. Louis.
He also was a four-year letterman at Oklahoma State, where he finished with 2,757 yards rushing and 27 touchdowns.
