Their six-game winning streak now snapped and the AFC West crown in jeopardy, the Oakland Raiders (10-3) will try to reignite their postseason hopes against the San Diego Chargers (5-8) when they kick off in Week 15 Sunday afternoon at Qualcomm Stadium.

Oakland and quarterback Derek Carr, in the worst game of his career, misfired in last week’s 21-13 loss at Kansas City that may have dashed a shot at the division title. Carr went 17-for-41 for 117 yards, no touchdowns, and a 49.1 passer rating and the Raiders' previously unstoppable offense put up only 244 total yards.

Kansas City now owns the season series against Oakland, which now likely requires a meltdown from the Chiefs over the next three weeks in order to re-take the AFC West and the conference’s No. 2 seed. However, Oakland’s in firm control of the AFC’s top wild card spot.

Quarterback Philip Rivers and the Chargers’ playoff chances have diminished over the last two games, falling to Tampa Bay at home and Carolina on the road, and they're currently three games back of Denver for the final wild card. But a win over the Raiders, who narrowly escaped Week 5’s matchup 34-31 for a third-straight comeback victory, could boost San Diego’s postseason aspirations — with some help from many other teams. San Diego hasn’t made the postseason since 2013 and only once since 2009.

San Diego may have to rely on Rivers' big arm even more, as starting running back Melvin Gordon seems unlikely to return from hip and knee injuries sustained against the Panthers. Instead, rookie Kenneth Farrow will start in the backfield after gaining 75 yards last week, and he stands to take advantage of Oakland’s No. 26-ranked rushing defense.

Farrow is also likely to face a Raiders front line that’s still dealing with injuries. Defensive tackle Darius Latham (ankle) was limited in Thursday’s practice and it appears fellow tackle Stacy McGee (ankle) could also miss his third straight game, CSN Bay Area reported.

Sensational rookie safety Karl Joseph (toe), who’s third on the team with 60 tackles, also appears “extremely likely” to sit out a second straight contest.

On the Chargers side, along with Gordon, cornerback Craig Mager (shoulder) and wide receiver Jeremy Butler (ankle) have missed each missed Wednesday and Thursday’s practice sessions.

Guard Orlando Franklin (rib) didn’t participate on Wednesday but returned on a limited basis on Thursday, potentially boosting Rivers’ odds of meeting Raiders star linebacker and pass rusher Khalil Mack face-to-face.

Mack’s been on a tear of late, recording 10.0 of his 11.0 sacks in Oakland’s last eight games and forcing fumbles five of the last six games.
