How Tolbert can impact CAR backfield

There is no getting around the fact that the Carolina Panthers backfield has been a banged up mess this preseason. DeAngelo Williams is healthy and good to go, but Jonathan Stewart still is recovering from surgery on both ankles and will remain on the PUP list for at least the first six games, sixth-round rookie Kenjon Barner is not expected to play through his nagging ankle injury this week, and Mike Tolbert missed the entire preseason with a hamstring injury.
