Titans QB Vince Young committed his third tunrover, an interception by Chargers FS Eric Weddle with 2:56 remaining in the third quarter. Three minutes later, on the first play of the fourth quarter, RB Darren Sproles scored his third touchdown to give San Diego a 42-10 lead, effectively putting the game out of reach.

Game ball

Not to be forgotten in the most valuable player conversation, Chargers QB Phillip Rivers was efficient and outstanding. He finished the game 21 of 27 for 264 yards and two touchdowns, spreading the ball around to nine different receivers and completing seven passes of more than 20 yards in what was essentially three quarters of play. The Chargers are now 18-0 in December with Rivers as their starter.
