The Seattle Seahawks are without another offensive starter as they take on the Cleveland Browns on Sunday.

In addition to quarterback Charlie Whitehurst getting his third career NFL start in place of Tarvaris Jackson, the team announced during the opening drive of Sunday's game that starting running back Marshawn Lynch injured his back during pre-game warm ups.

Leon Washington got the start in place of Lynch.

Lynch rushed for 98 yards and a touchdown on 12 carries in a 36-25 win over the New York Giants in Week 5.

The Oakland native has 239 yards and two touchdowns in five games this season.
