Veteran tackle Jon Jansen and rookie middle linebacker Caleb Campbell have confirmed via Twitter that they have been cut by the Lions today. The roster must be cut to 53 by 6 p.m.

Jansen, who grew up in Clawson, was in a battle during training camp to start at right tackle with Gosder Cherilus. Obviously the Lions have decided to go the younger route. They have liked Corey Hilliard in camp and they have rookie Jason Fox learning the ropes.

Campbell tweeted that he was told he’ll be on the practice squad. First he has to clear waivers. The Lions can name eight to the practice squad at noon on Sunday.

Campbell, who hadn’t played football in two years because of military obligations, was making a position change from safety to linebacker. This is in no way a surprise and a good move for Campbell.
