Carson Palmer looked like an NFL quarterback again, not like aguy who had settled into semi-retirement in SouthernCalifornia. Philip Rivers looked, well, like the turnover-prone quarterbackthat he’s been since opening day. Palmer threw two touchdown passes and Michael Bush ran 30 timesfor a season-high 157 yards and one touchdown to lead the OaklandRaiders to a 24-17 win over San Diego on Thursday night, theChargers’ fourth straight loss. The Raiders (5-4) broke a two-game losing streak and took ahalf-game lead over the Kansas City Chiefs in the AFC West. “I wouldn’t call it a must-win, but it was a big win for us,”Raiders defensive tackle Richard Seymour said. “These games in asense count twice. It’s a win and also it’s a win in the division.It gives us a leg up right now.” Palmer threw touchdown passes of 33 and 26 yards to DenariusMoore in his second start and third appearance since being acquiredin a trade with Cincinnati. He’d been semi-retired and living inDel Mar, just north of San Diego, before being traded. He livesnext door to Chargers coach Norv Turner. Palmer was 14 of 20 for299 yards, with one interception. Bush helped carry the load for the Raiders with running and alsohad three catches for 85 yards. The Chargers (4-5) looked dismal most of the night and lost lefttackle Marcus McNeill, right guard Louis Vasquez and linebackerTakeo Spikes to injuries. The Raiders have won three straight against the Chargers. Beforethat, San Diego had won 13 straight in a rivalry that dates to thebirth of the AFL. With the Chargers threatening to tie it, Rivers was interceptedin the end zone by Matt Giordano with 3:22 left. It was Rivers’NFL- and career-high 15th interception. Rivers was sacked onconsecutive plays near midfield to end the game. He fumbled on thefinal play, giving him an NFL-high 19 turnovers. Rivers was 23 of 47 for 274 yards. He was sacked six times asthe Raiders overwhelmed Brandyn Dombrowski, who replaced McNeill atleft tackle. “Obviously some of the offensive linemen went down and wesmelled blood and we just went after him,” Seymour said. “All week our defensive coordinator said, `Hey, they can scorefrom anywhere on the field and it’s going to be up to our defensivefront to get pressure on the quarterback,’” Seymour added. We knewwe could get it done but it was going to be a collectiveeffort.” The Raiders had 14-point leads in the second and third quarters,and San Diego could never quite catch up. San Diego struggled in the first half, going three-and-out fourstraight times after getting a 20-yard field goal by Nick Novak onthe opening drive. Rivers was only 4 of 11 for 44 yards for a passer rating of49.1. By comparison, Raiders punter Shane Lechler had a rating of39.6 by going 0 for 1. Sebastian Janikowski has a sore hamstring,so the Raiders tried a fake punt from the Chargers’ 34 on theirfirst drive. Lechler threw a pass to Jacoby Ford, who was mauled byQuentin Jammer because pass interference can’t be called in a puntformation. Bush scored on a 2-yard leap over the pile late in the firstquarter and Janikowski kicked a 23-yard field goal on the nextdrive. Palmer threw a 33-yard scoring pass to Moore for a 17-3 leadthat held up at halftime. The Chargers finally came to life on the first drive of thesecond half, capped by rookie Vincent Brown’s leaping catch of a30-yard touchdown pass in double coverage, his first NFL score, topull to 17-10. Rivers completed five passes on the drive, one more than he hadin the first half, and the Chargers gained 80 yards, compared to 65yards total in the first half. The Raiders pushed the lead to 24-10 on the next drive afterPalmer found Moore for a 26-yard score. Two plays earlier, Bushgained 55 yards on a screen pass. Brown appeared to come down with another great TD catch in thethird quarter, this one for 33 yards. But referee Ed Hochulioverturned it on replay, saying that since the defender landed outof bounds with his hand on the ball, it was considered out ofbounds. Three plays later, Rivers found fullback Jacob Hester for a7-yard TD pass to pull to 24-17.
