Marshall (concussion) practiced in full Wednesday, Darin Gantt of the Panthers' official site reports.

Marshall remains in the NFL's five-step concussion protocol, but considering his full activity to begin Week 9 prep, he's closing in on gaining clearance from an independent neurologist. He's been sidelined the past two games due to the head injury, but his absence hasn't had a trickle-down effect on depth receivers Shi Smith and Alex Erickson, who have combined for one catch and three targets during that stretch.
