Philip Rivers and the Los Angeles Chargers are on the move. Dak Prescott and the Dallas Cowboys are fading fast.

Rivers threw for 434 yards and three touchdowns in his first Thanksgiving game in his 14th season and the Chargers beat the fading Cowboys 28-6 on Thursday.

Desmond King returned an interception 90 yards for the punctuating touchdown as the Chargers (5-6) moved within one and a half games of AFC West-leading Kansas City after starting 0-4 while the Chiefs won their first five.

The defending NFC East champion Cowboys (5-6) lost their third straight by at least 20 points, all without star running back Ezekiel Elliott, in a damaging defeat for their fading playoff hopes.

Dallas, playing its 50th Thanksgiving game, finally ended a touchdown drought at a team-record 10 quarters on Rod Smith’s two-yard run early in the fourth quarter. The Cowboys have been outscored 72-6 in the second half of the three losses.

Keenan Allen had a career-high 172 yards on 11 catches with a touchdown, giving him 23 grabs for 331 yards and three scores in the past two games.

Prescott has looked lost without Elliott, his backfield mate for a pair of remarkable rookie seasons that led the Cowboys to the best record in the NFC last season. Prescott had two interceptions, giving him five in two games after throwing just four a year ago.

Last year’s NFL Offensive Rookie of the Year has nine picks for the season. Elliott is halfway through a six-game suspension for alleged domestic violence.

LA overcame the loss of kicker Nick Novak to a back injury, the second straight game that Dallas’ opposing kicker was injured and in the same game that Dallas’ Dan Bailey returned after missing four games with a groin injury.

Just like last week in the Cowboys’ blowout loss to division-leading Philadelphia, neither of the kickers mattered much with the Dallas offense sputtering and the defense not getting key stops.

Novak returned to make a 22-yard field goal after the injury, but left for good after missing an extra point. Punter Drew Kaser was one of three on extra points. The Chargers went for a fourth-and-13 in field goal range in a scoreless game early in the second quarter with Novak’s status in doubt, coming up a yard short.

Four-time Pro Bowl left tackle Tyron Smith returned for Dallas after missing two games with back and groin injuries, but the Cowboys lost 2014 All-Pro right guard Zack Martin to a concussion in the first half.

Rivers, who was 27 of 33 for a 149.1 passer rating without a sack, had seven completions of at least 22 yards.

That included Allen’s weaving 42-yard catch-and-run for a score when he ran past safety Jeff Heath on the sideline, cut between two more safeties in Xavier Woods and Byron Jones before past cutting inside cornerback Anthony Brown for a 22-6 lead.

Austin Ekeler had a 38-yard catch to set up San Diego’s first touchdown in the third quarter, and Tyrell Williams added a 31-yard grab before making a 27-yard scoring catch.

Vikings 30, Lions 23

Case Keenum stood in the pocket to take a hit, dipped his right shoulder to slip out of a sack and shuffled his feet in the pocket to give his receivers more time to get open.

Looking like a savvy winner, instead of a journeyman, he picked apart Detroit’s defense with his arm and made plays with his legs to help the Minnesota Vikings beat the Lions 30-23 Thursday.

Keenum threw for two touchdowns and ran for a score in the first half to give the Vikings a double-digit lead and they went on to win a seventh straight game.

They took a huge step toward winning the NFC North by taking a three-game lead over the second-place Lions.

Keenum, undrafted out of Houston in 2012, is suddenly 7-2 this season after going 9-15 with the Houston Texas and the St Louis/Los Angeles Rams.

“I want to be great and I have confidence in myself that I can be great,” he said.

The Vikings signed him to be a backup and he has made the most of his opportunities with Sam Bradford injured and Teddy Bridgewater recovering from a knee injury.

Keenum was 21 of 30 for 282 yards with both TD passes going to Kyle Rudolph, giving the Vikings a 20-3 lead late in the second quarter.

“Case is amazing because he does so many small things to pick up first downs and keep drives alive,” Rudolph said.

“Every time he finds a way to convert another third down, it means we’ve got three more plays to attack the defense. With the number of big-play guys we’ve got now, we can do a lot of damage with those three plays.”

Detroit (6-5) made mistakes in every phase of the game and Minnesota took advantage. Keenum’s one-yard pass to Rudolph was made a little easier because the Lions had just 10 defenders on the field.

And, Keenum’s nine-yard run came after Matthew Stafford was charged with a fumble while trying to hand off to Ameer Abdullah.

Instead of winning to pull within a game of Minnesota and having a potential tiebreaker, the Lions’ loss hurts their chances of making a second straight postseason appearance.

“Don’t count us out just yet,” Detroit coach Jim Caldwell said. “We’ve got a lot of football yet to play.”
