[Panthers] Did Panthers Mishandle C Ryan Kalil's Injury?

The Panthers have been eager to get C Ryan Kalil back on the field, but close observers of the team say it mishandled his return from an ankle injury. Carolina started Kalil in Week 10, but he aggravated the injury and had to leave the game. It set him back, we hear, and could keep him out for a longer period than would have been necessary had the Panthers remained patient.
