The Dallas Cowboys missed the chance to clinch a playoff berth as they suffered a stunning overtime loss to the Jacksonville Jaguars, who claimed a thrilling 40-34 win on a pick-six from Rayshawn Jenkins.
Dallas led 27-10 in the third quarter with a postseason place within their grasp, and had the chance to punch their ticket late in regulation despite 2021 first overall pick Trevor Lawrence leading a Jaguars turnaround with touchdown passes of 59 yards and three yards to Zay Jones, which were sandwiched by a 10-yard toss to Marvin Jones Jr.
Cowboys quarterback Dak Prescott spun out of the pocket and found a diving Noah Brown for a 13-yard connection that marked Brown's second touchdown catch of the day and restored the Cowboys' lead with just over three minutes remaining.
Lawrence then fumbled on an 11-yard scramble as the Jaguars tried to respond to seemingly gift the game to Dallas, only for the Cowboys to quickly go three and out and hand the Jags a final chance to tie the game.
They did just that as Lawrence hit Zay Jones again for 19 yards with five seconds remaining to set up a 48-yard Riley Patterson field goal, which levelled matters at 34-34.
An engrossing quarterback duel between one of the NFL's best and one of its future stars was settled by an interception as Prescott's short third-down pass bounced off Brown's hands and into the grasp of Jenkins, who sprinted 52 yards the other way to seal a remarkable win.
The Jags improve to 6-8, just a game back in the win column of the AFC South-leading Tennessee Titans, while the 10-4 Cowboys are still likely to make the playoffs but have a mountain to climb to win the NFC East, where they trail the Philadelphia Eagles by three games.
Chiefs, Eagles survive scares
The Kansas City Chiefs stunningly struggled to put away the one-win Houston Texans with the chance to clinch a seventh successive AFC West title.
It looked as if they may fall victim to the biggest upset of the season when Harrison Butker missed a game-winning 51-yard field goal to force overtime and Patrick Mahomes was sacked to give Houston the ball. However, Davis Mills fumbled the ball back to Kansas City on Houston's first offensive snap of the extra period, setting up Jerick McKinnon to seal a 30-24 win with a 26-yard walk-off touchdown run.
The Eagles were not pushed quite as far by the Chicago Bears, but another impressive dual-threat showing from Justin Fields meant the NFC's number one seed had to work hard for a 25-20 win, their 13th of a spectacular campaign, which was secured when A.J. Brown made his ninth catch of 181-yard display to convert on third down and allow Philadelphia to kill the clock.
Lions' surge continues as Jets let time run out
The Detroit Lions' hopes of an unlikely playoff berth were boosted once again as they claimed a dramatic sixth win in seven games to improve to 7-7.
Detroit dented the New York Jets' postseason prospects with a 20-17 win at MetLife Stadium, Jared Goff's 51-yard touchdown pass to Brock Wright on fourth down with 109 seconds remaining proving decisive.
The Jets, starting Zach Wilson once more in place of the injured Mike White, were left to rue poor clock management on the final drive, with Wilson's improvised 20-yard cross-field completion to Elijah Moore only progressing them to Detroit's 40-yard line with one second remaining. Greg Zuerlein's 58-yard field goal attempt drifted well wide, dropping the Jets to 7-7 after a 6-3 start.
