SAN FRANCISCO
The hits just keep coming for the Carolina Panthers’ banged-up offensive line.
The Panthers put starting center Ryan Kalil and his backup Gino Gradkowski on injured reserve Tuesday, further depleting a line that has been depleted by injuries much of the season.
Kalil has been dealing with a shoulder injury for the past month.
He missed two games -- including a homecoming game at Los Angeles -- before reinjuring the shoulder in a Nov. 17 win against New Orleans. Kalil, 31, a five-time Pro Bowler, did not make the trip to northern California.
