Freeling (concussion) was a full participant in Friday's practice but is listed as questionable for Sunday's game against the Lions, Alex Zietlow of The Charlotte Observer reports.
Freeling entered the league's concussion protocol following the Panthers' loss to the Browns in Week 3. He was cleared to fully practice Friday, but he needs to pass an evaluation by an independent neurologist in order to play Sunday. Stone Forsythe would likely start at right tackle if Freeling held out.
