Brutally bad weather or bitter cold meant good vibes for lots of NFL players.

The conditions in Philadelphia, Baltimore, Washington, Pittsburgh and Denver didn’t set back the Eagles, Ravens, Chiefs, Dolphins and Broncos on Sunday.

Most notable were the performances by Eagles star running back LeSean McCoy and Lions kick returner Jeremy Ross in blizzard-like conditions in Philly. McCoy ran for a franchise-best 217 yards, including touchdowns of 57 and 40 yards in a 34-20 victory over Detroit. The Eagles overcame two TD returns by Ross.

Also surviving the elements were the defending champion Ravens, 29-26 over Minnesota, which lost 2012 MVP Adrian Peterson to a foot/ankle injury; Kansas City with a 45-10 rout at Washington; and Denver, where Matt Prater broke the NFL record with a 64-yard field goal in a 51-28 romp past Tennessee that earned the Broncos a playoff berth.

Ravens 29, Vikings 26

At Baltimore, Joe Flacco threw a 9-yard touchdown pass to rookie Marlon Brown with 4 seconds left. Brown’s catch concluded a five-play, 80-yard drive that took only 41 seconds.

It came after Matt Cassel threw a 79-yard touchdown pass to Cordarrelle Patterson with 45 seconds remaining. Just before that, Baltimore’s Jacoby Jones took a kickoff 77 yards for a score, which followed a 41-yard touchdown run by Toby Gerhart, who had replaced Peterson for Minnesota (3-9-1).

Chiefs 45, Redskins 10

The visiting Chiefs scored on their first four possessions in the snow, sacked Robert Griffin III five times and Kirk Cousins once, and returned both a punt and a kickoff for a touchdown. Kansas City (10-3) snapped a three-game slide.

Broncos 51, Titans 28

At Denver, Peyton Manning threw four more touchdown passes in 14-degree weather. Prater kicked his record setter to close the first half and pull Denver within 21-20.

Patriots 27, Browns 26

Visiting Cleveland had the Patriots down all game, but folded.

Tom Brady threw two touchdown passes in the final 61 seconds and New England recovered an onside kick to set up the win.

Saints 31, Panthers 13

At New Orleans, Drew Brees passed for 313 yards and four touchdowns and the Saints regained sole possession of first place in the NFC South. They snapped the Panthers’ winning streak at eight games.

Bengals 42, Colts 28

At Cincinnati, the Colts (8-5) backed into the AFC South crown when the Titans fell.

Andy Dalton threw for three touchdowns and ran for another as the Bengals remained perfect at home and in control of the AFC North.

49ers 19, Seahawks 17

At San Francisco, Phil Dawson kicked a 22-yard field goal with 26 seconds remaining, denying Seattle (11-2) a chance to clinch the NFC West.

Packers 22, Falcons 21

At Green Bay, Wis., Matt Flynn threw for 258 yards and the Packers (6-6-1) snapped a five-game winless string.

Jets 37, Raiders 27

Geno Smith threw a touchdown pass and ran for another score as the host Jets (6-7) set a season high for points and stopped a three-game skid.

Chargers 37, Giants 14

At San Diego, Philip Rivers found rookie Keenan Allen for two of his three touchdown passes, and the Chargers (6-7) kept alive their long-shot playoff hopes.
