The Kansas City Chiefs withstood a late surge from the Miami Dolphins to come away with a division-clinching 33-27 victory.
Patrick Mahomes turned the ball over three times to keep the Dolphins in it, but his 393 yards and two touchdowns through the air proved just enough to help the Chiefs claim the AFC West for the fifth year in a row.
His combination with Travis Kelce again proved the difference for Kansas City as the tight end finished with 136 receiving yards and a touchdown.
Meanwhile Miami's rookie quarterback Tua Tagovailoa put together another strong performance, which included two late touchdown drives to bring the hosts within six, but ultimately ran out of time to complete the comeback.
After starting the season 11-0, the Pittsburgh Steelers were handed their second-straight defeat in a 26-15 loss to the Buffalo Bills.
Buffalo quarterback Josh Allen again impressed, throwing for 238 yards and two touchdowns, while his opposite Ben Roethlisberger was unusually sloppy.
Roethlisberger threw two crucial interceptions in the loss, one of which was a 51-yard pick six by Bills safety Taron Johnson which gave Buffalo a 9-7 lead at half-time.
The Philadelphia Eagles also pulled off a dramatic 24-21 upset victory against the New Orleans Saints.
Making his first career start, quarterback Jalen Hurts took it upon himself to help arrest Philadelphia’s four-game losing streak.
He threw for 167 yards and a touchdown and also picked up 106 yards on the ground to bring New Orleans’ nine-game unbeaten run to an end.
Tom Brady put together a timeless performance to lead the Tampa Bay Buccaneers to a gritty 26-14 win over the Minnesota Vikings.

A 316-yard effort from Derek Carr was not enough for the Las Vegas Raiders to defeat the Indianapolis Colts.
The 44-27 defeat puts the Raiders at risk of missing the play-offs.
