Carolina placed Christensen (Achilles) on injured reserve Thursday, Darin Gantt of the team's official site reports.
Christensen suffered a torn Achilles in this past Sunday's loss to Buffalo and underwent surgery Wednesday. Jake Curhan is currently atop the depth chart at right guard, though he could fade into a reserve once the Panthers get either Chandler Zavala (knee) or Robert Hunt (biceps) back from injured reserve.
