CHARLOTTE, N.C. (AP) - Panthers have announced that Pro Bowl center Ryan Kalil is out for the season after suffering a left foot injury.
Kalil was injured in Carolina's 16-12 loss to Seattle, although he continued playing.
Kalil went to see Dr. James Anderson on Tuesday and it was determined he had a Lisfranc injury, having torn a ligament that supports the middle of his foot.
He will have season-ending surgery on Monday and be placed on injured reserve.
A first-round draft pick by the Panthers in 2007, Kalil has been to the last three Pro Bowls and is a key cog in Carolina's offense. Coach Ron Rivera says Geoff Hangartner will move from right guard to center and either Garry Williams or Jeff Byers will play right guard.
Kalil made headlines during the summer when he took out a full-page ad in the Charlotte Observer guaranteeing a Super Bowl title for the Panthers this season.
