Hoping to increase their winning streak the Cardinals flew to Qualcomm Stadium for an interconference duel with the Chargers. In the 1st quarter the Cardinals trailed early as QB Philip Rivers completed a 33-yard TD pass to TE Antonio Gates, but they replied in the 2nd quarter when FS Kerry Rhodes recovered a fumble and ran 2 yards to the endzone for a touchdown. After that, the Cardinals fell further behind with FB Mike Tolbert making a 5-yard TD run, followed by Rivers making a 26-yard TD pass to TE Antonio Gates. The Cardinals had more problems when QB Derek Anderson's pass was intercepted by OLB Shaun Phillips which converted into a 31-yard touchdown run. This was followed in the 3rd quarter by kicker Nate Kaeding making a 48-yard field goal. Then RB Ryan Mathews got a 15-yard TD run. This was followed in the 4th quarter by Kaeding nailing a 47-yard field goal. The Cardinals tried to cut the lead, but only came away with kicker Jay Feely's 53-yard field goal, which isn't enough for the win.
