San Diego Chargers suffer key injuries

SAN DIEGO -- The San Diego Chargers' 24-17 comeback win over the Minnesota Vikings didn’t come without a cost.

ESPN’s Adam Schefter reports kicker Nate Kaeding -- who was hurt on a Percy Harvin touchdown return on the opening kickoff -- may have a torn ACL.

The San Diego Union Tribune reports defensive end Luis Castillo has a broken tibia. He will be out a significant amount of time, if not for the season.

Running back Mike Tolbert, who scored all three of San Diego’s touchdowns Sunday, has a knee injury. But it isn’t considered serious.

The Kaeding and Castillo injuries are of concern for the Chargers. The Chargers will need to sign a kicker and Jacques Cesaire and Vaughn Martin will play more for the Chargers now.
