The Oakland Raiders will have to look elsewhere for their new defensive coordinator.
Todd Grantham, who currently holds that position with Louisville, turned down the offer to join Jack Del Rio's staff, according to FOX Sports' Bruce Feldman.
Todd Grantham: "My family loves it in Louisville, and I think we are establishing something special here with Bobby Petrino and our staff."

The Cardinals had the sixth ranked defense, allowing just 308.5 yards per game.
