Andy Reid sends clear message to Kansas City Chiefs team after unbeaten run is abruptly ended by Buffalo Bills

ANDY Reid wants his Kansas City Chiefs team to learn from their painful defeat Sunday.

And Patrick Mahomes promised to use the loss against the Buffalo Bills as fuel for the rest of the season.

Kansas City's unbeaten start to the season was ended by Buffalo in a 30-21 loss Sunday.

The Chiefs started the season 9-0 and were unbeaten in 15 NFL games dating back to last September.

But Josh Allen's late touchdown run sealed victory for the Bills in the AFC showdown in western New York.

Kansas City had a number of miscues in the game.

And Reid urged his team to learn from their mistakes and get better in the second half of the season.

The margin between winning and losing is small and that starts with me," Reid said.

"It's a great game to learn from for some of our young guys.

"The main thing is they're a good team and if you have mistakes they get capitalized on.

"We have got to learn from it and take something out of it to make us better down the road."

The Chiefs coach added, "My hat goes off to Sean (McDermott) and the Bills.

"They did a nice job and they made plays when they needed to."

Mahomes threw for 196 yards, three touchdowns and two interceptions in Sunday's loss.

The Chiefs quarterback was asked about the team's unbeaten season ending.

"The undefeated thing was cool, but that's not our ultimate goal," he declared.

"We'll keep building toward that.

The main thing is they're a good team and if you have mistakes they get capitalized on.

"That's a good football team. Nothing to hang your head on losing to them," he added.

"We feel like we can play better.

"So we'll get back to work and try to use this as a spark so we can be a better football team in the end."

The Chiefs take on the Carolina Panthers in their next game.

They are seeking to become the first team in NFL history to win three straight Super Bowl titles.
