The Carolina Panthers have activated running back Jonathan Stewart off the physically unable to perform list. "I've been activated it's go time!" Stewart wrote on his Twitter account Saturday. Stewart suffered an ankle injury last November against Philadelphia and missed the last five games of the season, then underwent surgery in the offseason.

Having Stewart and DeAngelo Williams along with Cam Newton in your backfield could be what this team needs to make up for a lack of a #2 WR who's worth a damn.
