The Dallas Cowboys blew out their division rivals to go top of the NFC East, while the Buffalo Bills relied on a late penalty to skirt past the Kansas City Chiefs in a thrilling Week 14 slate of action.
A week on from their 42-19 mauling at the hands of the San Francisco 49ers, the Philadelphia Eagles were dealt another damaging defeat and this time lost their long-time leadership of the NFC East to boot.
The Dallas Cowboys dominated Sunday's high-profile matchup in Arlington, impressing on offense, defense and special teams in a 33-13 win that few anticipated.
Dak Prescott threw for 271 yards and two touchdowns as the Cowboys converted all four of its first-half possessions into points.
CeeDee Lamb and Michael Gallup were the recipients of Prescott's TD tosses while Rico Dowdle added a rushing touchdown in a first half that got away from the Eagles quickly.
Philadelphia's offense misfired again, committing three costly fumbles, one from Jalen Hurts and the other two from A.J. Brown and DeVonta Smith, all in Cowboys territory.
And even Dallas' former soccer-playing placekicker Brandon Aubrey came up big on the day as he became the first kicker in NFL history to hit two field goals of 59-plus yards in the same game.
It was the Eagles' second-largest loss with Jalen Hurts at quarterback and, following hot on the heels of the largest, should set further alarm bells ringing in the City of Brotherly Love.
Both teams now sit on 10-3 records with Dallas holding first place based on having the best win percentage in division games, but Philadelphia will retain the NFC East crown if they win out because that would give them the superior conference record.
The Niners, who proved too hot for the Seattle Seahawks again this week, are +120 to take the NFC crown with the Eagles at +300 to retain it and the Cowboys at +400 to make their first Super Bowl appearance since the 1995 season.
The Kansas City Chiefs' season continued to unravel against Buffalo as Patrick Mahomes and co suffered a 20-17 setback in a wild finish that dealt the reigning Super Bowl champions their third defeat in four games.
Mahomes later made his feelings known on the offensive offsides call that negated a go-ahead touchdown that would have put the Chiefs back in front with around 70 seconds left in the contest.
Kadarius Toney was lined up incorrectly and flagged as soon as the ball was snapped before he eventually benefitted from a crazy Travis Kelce lateral to scamper into the end zone.
Andy Reid wasn't happy either, calling it "a bit embarrassing for the National Football League for that to take place."
His opposite number Sean McDermott let out a primal scream on the sideline as his team moved to 7-6 to stay in the Wild Card mix.
He thanked his players for having his back after a week in which an article based on interviews with 25 anonymous Bills players, coaches and staff portrayed him in a less than favorable light.
The Baltimore Ravens survived a scary experience at home to the Los Angeles Rams to pull ahead of the Miami Dolphins, who host the Tennessee Titans on Monday night, in the AFC pecking order.
Baltimore needed overtime and a 76-yard punt return touchdown by backup returner Tylan Wallace to get it done against Matthew Stafford and the Rams' high-octane offense.
Lamar Jackson completed 24 of 43 passes for 316 yards, finishing with three touchdowns and one interception. A fortnight after he became the fastest quarterback to ever reach 5,000 rushing yards in the NFL, he also led the Ravens on the ground with 70 yards on 11 carries.
Odell Beckham Jr. reminded Rams fans of what they once had with 97 yards and a touchdown on four catches, while second-year tight end Isaiah Likely caught five passes for 83 yards and a score.
In wet conditions not ideally suited to passing, Stafford finished with 294 yards and three touchdowns but it was the unheralded Wallace, filling in for injured returner Devin Duvernay, who proved to be the unlikely hero as he slipped tackles and kept his feet on the sodden surface to author only the fourth overtime punt return TD in NFL history.
It wasn't all fun and frolics in the rain on Sunday as the New York Jets and Houston Texans failed to get into scoring position for the first 30 minutes of their Metlife Stadium matchup, which became the first NFL game to remain scoreless at the half in four years.
The Jets, who had scored just four touchdowns in their previous seven games, eventually broke out of their offensive funk as a resurgent Zach Wilson produced his best-ever performance as a pro to lead them to a surprise 30-6 win.
Over in Las Vegas, the Raiders and Minnesota Vikings were about to embark on a game that was to remain scoreless until the final two minutes when Greg Joseph slotted a 36-yard kick through the posts to send the visitors home happy.
It was the league's lowest-scoring game since Pittsburgh beat Miami on November 26, 2007 and only the third to finish 3-0 in the past 40 years.
