ALAMEDA, Calif. -- Of the three remaining teams on the Oakland Raiders regular-season schedule, left tackle Donald Penn might be most worried about this weeks game in San Diego.The Chargers (5-8) have the fourth-worst record in the AFC, are the only team in the West already eliminated from playoff contention and are riding a two-game losing streak.Yet Penn says you wouldnt know it from watching San Diego on film. For that reason alone, Penn has his concerns heading into Sundays road game.The thing is, you watch their film, theyre playing still like theyre in the mix of things and thats the scary part, Penn said Thursday.We have to make sure we go in there and take care of our business and make sure were on point with everything and dont take these guys lightly.That shouldnt be a problem considering that Oakland has a chance to clinch its first playoff berth since 2002. Beating the Chargers puts the Raiders in; a loss and theyll need some help to qualify this weekend.Oakland won the first matchup earlier this season when San Diego botched a potential game-tying field goal late in the fourth quarter.That game at the Oakland Coliseum in Week 5 also marked the debut of Chargers first-round pick Joey Bosa. Bosa had two sacks of the Raiders Derek Carr and had three tackles for losses on the day.Penn spent part of the game matched up against Bosa and will face him again on Sunday. Because the Chargers like to move Bosa around on the defensive line, Raiders right tackle Austin Howard will get his shot at Bosa, too.They dont get talked about enough, but they have a lot of good guys on their (defense), Penn said.Bosas really come along this year. He moved all over in that game. Hes been doing that all year. Hes still moving around on the film I watch.The Raiders offensive line has held up well for most of the season, allowing just 13 sacks in 13 games -- the fewest in the NFL. That should make for another intriguing matchup.The biggest group we faced this year, Bosa said of Oaklands offensive line. Tough group. Theyll maul you off the ball if youre not playing good technique and youre not playing fundamentally sound. We just have to come into this game and attack it the same way we did in Week 5.While San Diego is making a final push before heading into the offseason, the Raiders are trying to rebound from one of their worst games of the season after losing 21-13 in Kansas City last week.Penn doesnt think that will be an issue against a division rival.I think thats why weve been successful because we dont look ahead, Penn said. We take it one week at a time. Thats big, especially with having a young team like we do.Its big because some of the young guys could start thinking ahead, start looking ahead. But keeping that even keel, going week by week, gets you to focus more on that week and on that plan.Game notesFirst-round pick Karl Joseph (toe) did not practice and was seen walking gingerly in the Raiders locker room.
