Chargers 34, Cardinals 31

San Diego's Bryan Walters caught a 14-yard pass from Billy Volek to give the Chargers a 34-31 preseason victory over the Arizona Cardinals on Saturday night. The chemistry that Kevin Kolb and Larry Fitzgerald keep talking about was on full display early for the Cardinals. They connected on an 80-yard play for the quarterback's first touchdown pass with his new team. Later, though, San Diego's reserves scored with 3 seconds to play to win it. Philip Rivers completed 18 of 28 passes for 198 yards and two touchdowns for the Chargers as both teams played their first units well into the third quarter. Chargers tight end Antonio Gates, in his first game since Dec. 5, caught two for 18 yards, including a 13-yarder for a touchdown.
