Reigning champion Kansas City edged Carolina and Detroit ripped Indianapolis on Sunday to reach an NFL-best 10-1 while Dallas shocked arch-rival Washington to snap a five-game losing streak.

Patrick Mahomes threw for 269 yards and three touchdowns and Spencer Shrader kicked a 31-yard field goal on the final play to lift Kansas City over the host Panthers 30-27.

Chuba Hubbard's 1-yard touchdown run and a 2-point conversion run had put Carolina level with just under two minutes remaining, setting the stage for the Chiefs' seven-play, 57-yard march to set up the winning kick.

Joining the Chiefs with a 10th triumph to keep a conference lead was Detroit, with Jahmyr Gibbs rushing for 90 yards and two touchdowns and David Montgomery running for another score in the Lions' 24-6 triumph at Indianapolis.

A wild finish with 38 points in the last 5:16 marked the Dallas Cowboys' 34-26 victory at Washington, where the Commanders appeared to have lost, then made an amazing comeback only to fall in the end.

Cooper Rush's second touchdown pass, a 22-yarder to Luke Schoonmaker with five minutes remaining, gave Dallas a 20-9 edge, but Jayden Daniels threw a 4-yard touchdown pass to Zach Ertz and ran for a 2-point conversion to pull Washington within 20-17.

KaVontae Turpin answered with a 99-yard kickoff return touchdown on the ensuing play, but again the Commanders responded as Austin Seibert kicked a 51-yard field goal and Daniels connected with Terry McLaurin on an 86-yard touchdown pass with 21 seconds remaining.

Seibert, however, shockingly missed the conversion kick to keep Dallas ahead 27-26 and the Cowboys added a Juanyeh Thomas 43-yard kickoff return touchdown on the next play to seal victory. (AFP)
