Floyd caught a 22-yard touchdown from Rivers on the game's third play from scrimmage, and San Diego held on for a lackluster 13-6 win over Oakland. Both teams punted nine times, with Chargers punter Mike Scifres pinning the Raiders inside the 20 on five of his kicks. U-T San Diego lauded Scifres' performance, stating that he "arguably was the team MVP." San Diego was a season low 27% (4-for-15) on third-down conversions, after entering the game fourth best in the league (48%). Gates made a difficult catch late in the fourth quarter to extend a drive and help seal the game. San Diego linebacker Donald Butler recovered a fumble on the opening play of the game after Carr mishandled the snap from the shotgun formation. Two plays later, River lobbed a pass to Floyd, who leaped over T. J. Carrie for the score. The Chargers went up 10-3 after Novak kicked a 23-yard field goal to extend his team record to 32 consecutive field goals; however, he was wide left on a 48-yard attempt as the half ended. Rivers was injured after completing a 28-yard pass to Floyd in the third quarter, but the play was called back on a holding call against tackle King Dunlap. The Chargers settled on a 52-yard field goal by Novak for a 13-3 lead. The Raiders knocked the wind out of Rivers in the fourth, but he remained in the game after Oakland pulled with a touchdown with a 25-yard field goal from Sebastian Janikowski with four minutes remaining. On the following drive, Gates converted a key third-and-3 with a 15-yard catch at the Oakland 45 after tipping the pass to himself between safeties Charles Woodson and Brandian Ross. An incompletion would have forced a punt with 2:32 left; instead, Oakland need to use their remaining timeouts before receiving the ball back with 65 seconds to go. Carr threw a desperation pass that was incomplete short of the end zone as the game clock expired. Scifres' nine punts, which were the second most of his career, included ones that pinned the Raiders at their 2-, 4-, 6- and 8-, and 12-yard line. Oakland crossed midfield just twice in the game. San Diego started four drives on their 41-yard line or better, which netted only three punts and a field goal. Rivers was 22 of 34 for 193 yards. After saying that Rivers had been suffering a "very severe rib injury" for weeks, Gates later said he was "taken out of context". According to McCoy, Rivers had not missed any practice time nor received any treatment from the team trainer. After being out since September, Ryan Mathews, Manti Te'o and Melvin Ingram played for the Chargers. After missing seven games, Mathews ran 16 times for 70 yards, bolstering a running game that was averaging a league-low 3.1 yards per carry.
