Panthers' Jonathan Mingo: Limited in practice again

Mingo (concussion) was a limited participant in Thursday's practice.

Mingo's limited participation represents no change from Wednesday, suggesting he hasn't taken a tangible step forward in the past 24 hours as he navigates the NFL's five-step concussion protocol. If the wideout practices fully Friday and is able to gain clearance from an independent neurologist, he should exit the protocol and have a good shot at playing Sunday versus the Vikings.
