Carolina Panthers center Ryan Kalil is questionable to play in Thursday's game against the New Orleans Saints due to a shoulder injury.
Kalil missed the Panthers' last two games with the ailment.
Fellow center Gino Gradkowski is also listed as questionable with a knee injury.
Chris Scott is expected to start at center if neither Kalil or Gradkowski are available.
Linebacker A.J. Klein, left tackle Michael Oher, and safety Colin Jones are all ruled out with concussions.
