Three different finishes shaped Sunday's late NFL window. Arizona needed its kicker on every scoring possession, Buffalo needed one more touchdown drive after surrendering a lead, and Kansas City needed its defense to keep the Chargers from making a game of it.
The Cardinals beat the Rams 18-16, the Bills edged the Raiders 33-30 and the Chiefs handled the Chargers 22-6. Those results left Kansas City unbeaten at 5-0 and Buffalo 5-1, while Arizona ended a four-game losing streak.
Ryland supplies all 18 Arizona points
Chad Ryland made six field goals, including a 43-yard winner as time expired. The Cardinals never scored a touchdown and still won after the Rams moved ahead with 47 seconds remaining.
Matthew Stafford's 6-yard touchdown pass to Colby Parkinson put Los Angeles in position to win. Punter Ethan Evans converted the extra point because Blake Grupe had injured his knee tackling on a kickoff.
Jacoby Brissett answered with a 21-yard completion to Jalen Brooks, and a 15-yard unnecessary-roughness penalty added valuable field position. A five-yard Tyler Allgeier run helped set up Ryland's final attempt.
