The Chargers will apparently be without starting center Nick Hardwick until at least December and perhaps the rest of this season.
Sources said the team will announce later today that Hardwick is having surgery today on his left ankle and will be out at least eight weeks.
It is not known whether the Chargers will place Hardwick on injured reserve. They could decide to save a roster spot in case he can come back to help for a possible postseason run.
The Chargers last week lost nose tackle Jamal Williams, the cornerstone of their defense, for the season with a triceps tear.
Hardwick was injured in the third quarter of the Chargers’ season-opening victory at Oakland.
Scott Mruczkowski has been filling in for Hardwick and will continue to do so, though it is not known whether they will try to find depth behind him. Their backup center currently is Dennis Norman, who was signed last week.
Hardwick is undergoing the procedure in Indianapolis with the same surgeon that repaired his foot after the 2007 season.
