Coming off their MNF home win over the Jets, the Chargers flew to Oakland-Alameda County Coliseum for a Week 4 AFC West duel with the Oakland Raiders.  In the first quarter, the 'Bolts trailed early as Raiders kicker Sebastian Janikowski got a 22-yard field goal, along with Safety Gibril Wilson sacking QB Philip Rivers in his endzone for a safety.  In the second quarter, San Diego continued to trail as QB JaMarcus Russell completed a 63-yard TD pass to TE Zach Miller, along with Janikowski's 28-yard field goal. In the third quarter the Chargers began to rally as kicker Nate Kaeding made a 28-yard field goal.  In the fourth quarter, the 'Bolts continued their rally as Rivers completed a 9-yard TD pass to TE Antonio Gates, along with RB LaDainian Tomlinson getting a 13-yard TD run (with a successful 2-point conversion pass from Rivers to RB Darren Sproles).  Oakland tried to respond as Janikowski got a 32-yard field goal, yet San Diego completed its comeback with Kaeding making a 47-yard field goal and Tomlinson rushing for a 41-yard TD run. Notable: Through 15 games against a single opponent, LaDainian Tomlinson set a new record in touchdowns and yards against an opponent previously held by Barry Sanders, 1,763 yards, and Marcus Allen, 20 Touchdowns, respectively, by totaling 1,815 yards and 21 touchdowns. In this game, Janikowski attempted and failed a 76-yard field goal.
