Campbell, who was benched halfway through the second game of the season, replaced an injured Bruce Gradkowski late in the first quarter. Gradkowski injured his shoulder after being hit by Shaun Phillips and was in for only three plays the rest of the way.

Campbell completed 13 of 18 passes for 159 yards and a 1-yard touchdown to Zach Miller, leading drives of 93 and 73 yards in the second half to give the Raiders the lead. The biggest play on the winning drive came when Campbell found Brandon Myers for a 12-yard gain on fourth-and-1 from the San Diego 24. Bush, who ran for 104 yards in place of the injured Darren McFadden, finished it from there.

Rivers' 41-yard touchdown pass to Floyd midway through the third quarter gave the Chargers a 24-15 lead. With Vincent Jackson sitting out in a season-long contract dispute, Floyd delivered the big plays at receiver that have been lack for San Diego this year He also caught passes of 34, 36 and 55 yards.

The Raiders responded with the 97-yard drive. Campbell converted a third-and-1 sneak to get the drive going and then connected on a 58-yard pass to Louis Murphy to move the Raiders deep into Chargers territory.

Campbell did a good job extending a play on third-and-goal from the 1, finding Miller in the back of the end zone for the score that was upheld after a San Diego challenge.

The Raiders answered again after a field goal by Nate Kaeding early in the fourth quarter with their final drive.

The Chargers got off to a disastrous start, having two punts blocked in the first quarter, leading to a safety and touchdown for Oakland. They also lost a pair of fumbles deep in Raiders territory to fall into an early 12-0 hole.

But they still managed to take a 17-15 lead when Rivers drove them to a 43-yard field goal by Kaeding in the closing seconds of the half.
