Panthers general manager Dave Gettleman told the Charlotte Observer that he's not sure if running back Jonathan Stewart will be ready for the start of training camp. Stewart has already missed all of the OTA and minicamp practices after offseason surgery on his ankles. 

"We'll see," Gettleman said. "Time will tell."

DeAngelo Williams would likely see a bump in work if Stewart were to miss any time with Mike Tolbert and rookie Kenjon Barner also getting a chance at some carries.
