Titans 20, Chargers 17: Justin Hunter hauled in a 34-yard touchdown pass with 15 seconds left as host Tennessee stunned San Diego.

Facing a third-and-10, Jake Locker heaved a pass to Hunter in the end zone for his first career NFL reception to cap a 10-play, 94-yard drive. Locker went 23-for-37 for 299 yards while Nate Washington added eight catches for 131 yards to pace the Titans (2-1).

Philip Rivers completed 20-of-24 passes for 184 yards and a score for the Chargers (1-2), who converted just three of nine third-down opportunities. Antonio Gates led the way with five catches for 55 yards and a touchdown.

San Diego hit the scoresheet just over five minutes into the game as Rivers capped a short drive with a 7-yard scoring strike to Gates. The teams traded second-quarter field goals before the Titans drew even on Locker's 7-yard touchdown run with 1:08 remaining in the half.

The Chargers surged back in front late in the third quarter as Rivers' 34-yard strike to Ladarius Green set up Ronnie Brown's 1-yard touchdown plunge. Rob Bironas' 37-yard field goal with 6:07 left in the fourth made it 17-13, and the Titans were given an opening to win after the Chargers managed just 18 yards on seven plays on the ensuing drive.
