The Chargers signed kicker Nick Novak on Friday, after Nate Kaeding cut practice short because of a groin injury, a source said. Novak was on the team's flight to Kansas City for Sunday's game against the Chiefs. The Chargers listed Kaeding (groin) as questionable on their injury report. Kaeding, who'd gone 7-for-7 on field goals, hadn't been on an injury report this season. "He was sore when he started kicking today, and wasn’t able to continue," coach Norv Turner said.
