SAN DIEGO (AP) – Chargers coach Norv Turner says kicker Nate Kaeding is out for the year after injuring his left knee during the season’s opening kickoff.  Kaeding, a former Iowa Hawkeye star, entered the season as the most accurate kicker in NFL history, having made 86.5 percent of his field goal attempts in the previous seven seasons.  Minnesota’s Percy Harvin returned the opening kickoff 103 yards for a touchdown. The Chargers rallied to beat the Vikings 24-17.  Punter Mike Scifres took over placekicking duties and made his
first NFL field goal, a 40-yarder.  Turner says the Chargers have a list of possible replacements for Kaeding.
