"Steelers nose tackle Casey Hampton said he will have surgery Friday to repair a torn anterior cruciate ligament in his left knee, an injury he sustained in the season-ending playoff loss in Denver.

The Steelers had indicated that Hampton would not need knee surgery, but the five-time Pro Bowl nose tackle told the Pittsburgh Post-Gazette today he will have the surgery to repair his ACL.

It will be the third time Hampton has had ACL surgery, two of which came during his Steelers career. It is the second time he has had the surgery on his left knee."
