NFL round-up: Bills down Chiefs in thriller as Ravens and Cowboys win
A 39-yard field goal from Tyler Bass with one minute and 54 seconds remaining sealed victory for Allen and the Bills at the Chiefs' Arrowhead Stadium in another absorbing encounter between the two rivals.
The Bills survived a scare on the Chiefs' final drive. A superbly worked touchdown saw tight end Travis Kelce toss a lateral pass to send Kadarius Toney racing into the end zone, but it was ruled out for offside.
The score was disallowed and Chiefs quarterback Patrick Mahomes was unable to move the chains to leave Buffalo celebrating a win that leaves them on 7-6 and second in the AFC East.
Bills quarterback Allen could not hide his relief at the disallowed touchdown that enabled Buffalo to claim a hard-fought victory.
"That might have been the craziest play I've ever seen in my life," Allen said of Kelce's lateral pass.
"We got a win, we've obviously got some things to clean up, but we'll take it. We just rallied behind each other, played for each other. Wish we'd scored some more points but a win's a win."
Allen threw one touchdown and rushed for another to finish with 233 passing yards from 23 completions.
Opposite number Mahomes had a relatively quiet day, with one touchdown and an interception for 271 yards as the reigning Super Bowl champions fell to a second straight loss.
Walkoff punt return
In Baltimore, a Tylan Wallace punt return touchdown in overtime sealed a thrilling 37-31 victory for the Ravens over the Los Angeles Rams that moved the Ravens into pole position in the AFC play-off race.
Wallace's 76-yard dash for glory helped the Ravens improve to an AFC-best record 10-3, boosting their chances of claiming top seeding in the play-offs.
"You never know when your moment's gonna come, so when it does you just take advantage of it," Wallace said.
The walkoff touchdown was the final act of a wild game that saw the lead change hands eight times in regulation.
The Rams forced overtime with a Lucas Havrisik field goal with seven seconds remaining that tied the score at 31-31 after the Ravens had snatched the lead late in the fourth quarter thanks to a Zay Flowers touchdown and a two-point conversion to make it 31-28.
Ravens quarterback Lamar Jackson completed 24 of 43 passes for 316 yards and three touchdowns with one interception.
In Dallas, the Cowboys made a statement with a 33-13 victory over Philadelphia that pulled them level with the Eagles atop the NFC East at 10-3.
The Cowboys led from wire-to-wire, with quarterback Dak Prescott connecting with CeeDee Lamb on a 13-yard touchdown pass to cap their opening drive.
Prescott threw for 271 yards and two touchdowns and the Dallas defense put on a clinic as the Cowboys avenged a 28-23 loss to Philadelphia last month.
Prescott hit Michael Gallup with a one-yard TD pass in the final minute of a first half that also featured a one-yard touchdown plunge by Dallas' Rico Dowdle and saw the Cowboys up 24-6 at the break.
Dallas kicker Brandon Aubrey remained perfect for the season, booting four field goals that included one of 60 yards and a 59-yarder.
Philadelphia, limited to two field goals from Jake Elliott in the first half, scored their only touchdown when Jalen Carter grabbed a Prescott fumble and ran it 42 yards for a score in the third quarter.
The Eagles, who coughed up three fumbles, wouldn't score again.
NFC West leaders San Francisco also improved to 10-3 with a convincing 28-16 home win over the Seattle Seahawks.
Quarterback Brock Purdy threw two touchdowns with 368 yards while running back Christian McCaffrey rushed for 145 yards.
In Las Vegas, the Raiders and the Minnesota Vikings came within a whisker of the first 0-0 scoreline of the NFL's Super Bowl era before Greg Joseph's 36-yard field goal with 1:57 on the clock gave the Vikings a 3-0 victory.
The result was the lowest-scoring game since Pittsburgh defeated Miami by the same scoreline in 2007. The last time a game finished 0-0 after four quarters was in 1943.
