The San Diego Chargers dominated divisional rival Oakland 34-7 on Thursday to keep their slim postseason hopes alive. Quarterback Phillip Rivers threw three touchdown passes and LaDainian Tomlinson rushed for 91 yards and a score to help San Diego (5-8) snap a three-game losing streak. The Chargers trail the Denver Broncos by two games in the AFC West and have three regular season games remaining, one of which is against the Broncos on Dec. 28. Denver (7-5) plays Kansas City on Sunday. San Diego will almost certainly have to win its remaining games to have any chance of making the playoffs. On Thursday, Rivers quickly found his rhythm against an inept Raiders defense, connecting with Darren Sproles for an eight-yard score and Vincent Jackson on a 59-yard bomb in the second quarter. Jackson finished with five catches and 148 yards receiving. Oakland (3-10) also struggled offensively, and quarterback JaMarcus Russell left the game in the second quarter with an ankle injury after throwing two interceptions. The Raiders' lone score came from Justin Miller, who took a kickoff and ran 92 yards for a touchdown just before halftime. Sproles capped the scoring with a second touchdown reception, an 18-yard catch with 7:19 left in the fourth quarter.
