Hoping to rebound from their shutout home loss to the Jets, the Raiders flew to Qualcomm Stadium for a Week 8 AFC West rematch with the San Diego Chargers.  Oakland would trail in the first quarter as Chargers running back LaDainian Tomlinson got a 6-yard touchdown run.  The Raiders answered in the second quarter as running back Justin Fargas got a 5-yard touchdown run, but San Diego replied with quarterback Philip Rivers' 8-yard touchdown pass to wide receiver Vincent Jackson and Tomlinson's 10-yard touchdown run.  Afterwards, Oakland would close out the half as kicker Sebastian Janikowski got a 48-yard field goal. In the second quarter, the Raiders tried to rally as Janikowski nailed a 41-yard field goal in the third quarter and a 28-yard field goal in the fourth, but the Chargers pulled away with a 28-yard field goal from kicker Nate Kaeding. With the loss, Oakland fell to 2-6 entering their bye week.
