Carolina tight end Kris Mangum could be out for several weeks with plantar fasciitis in his left foot.
After struggling with the injury during the first few days of camp, Mangum is now in a cast and limping around in a walking boot.
"I wasn't doing it any good out there; it was just getting worse and worse," Mangum said. "Hopefully this takes care of it. It's definitely an aggravating injury."
Mangum said he was told to wear the cast for a couple of weeks. He's still hopeful he can play an exhibition game.

LAWSUIT: On Thursday, an appeals court overturned a landmark $105 million verdict against a stadium vendor that sold beer to a drunken fan who later paralyzed a girl in an auto wreck.
The family claimed that vendors for Philadelphia-based Aramark Corp. continued to sell beer to Daniel Lanzaro during a 1999 New York Giants game even though he was clearly drunk, and that the concessionaire fostered an atmosphere in which intoxicated patrons were able to still buy alcohol.
