Darren Sproles' long kickoff return set up Nate Kaeding's go-ahead 47-yard field goal with 1:51 to play and LaDainian Tomlinson sealed the Chargers' 10th straight win over their AFC West rivals with a 41-yard scoring run in a 28-18 victory.
The streak by San Diego (2-2) is the longest any team has held against Al Davis' once-proud franchise. Kiffin's job security had been in question even before the Raiders (1-3) blew a nine-point lead in the fourth quarter last week against Buffalo.
Tomlinson overcame a slow start to put together another strong performance against the Raiders, running for 106 yards and two scores.
Quoteworthy: "It wasn't our prettiest win, but our defense gave us a chance." -- Philip Rivers, Chargers quarterback
