Kansas City Chiefs quarterback Patrick Mahomes says his side will be ready to win during the playoffs irrespective of whether they claim the AFC's top seeding.

The Chiefs improved their record to 12-5 with Saturday's 28-24 win over the Denver Broncos, which was Kansas City's 13th straight road win against AFC West opposition.

The result means the Tennessee Titans have to beat the Houston Texans on Sunday to move above the Chiefs to claim the AFC's top seed.

"We'll watch the game and everything like that," Mahomes told ESPN after the game.

"We handled our business today. We'll see what happens tomorrow. Regardless we'll be ready to win some football games."

The Chiefs may have clinched the top seed on Saturday had they not gone down 34-31 to the Cincinnati Bengals last weekend, snapping their eight-game win streak.

Mahones, who threw two touchdowns and completed 27 of 44 passes for 270 yards, said the Chiefs needed to improve if they were going to make a long playoffs run.

"We've got to be better. We've got what it takes," Mahomes said.

"We've got everybody in the locker room to do what we want to do but we've got to be better if we want to make a run through the AFC because it's a tough division."

The Chiefs appeared in danger of a loss to the Broncos until ex-Los Angeles Chargers linebacker Melvin Ingram's tackle on Broncos running back Melvin Gordon forced a fumble which rookie Nick Bolton scooped and scored from in the fourth quarter.

"That was a heck of a play by Melvin Ingram," Mahomes said. "That's the reason why we got him here. He makes plays like that."

Patrick Mahomes threw two touchdown passes but Missouri rookie Nick Bolton came up with the key play as the Kansas City Chiefs kept their AFC top seeding hopes alive with a seesawing 28-24 win over the Denver Broncos.

Bolton delivered a 86-yard scoop and score to give the Chiefs a lead they would not relinquish in the fourth quarter after Melvin Ingram's tackle forced a fumble from Broncos running back Melvin Gordon.

The result means the Chiefs (12-5) will claim the AFC top seed if the Tennessee Titans (11-5) fail to beat the Houston Texans on Sunday.

The victory was also the Chiefs's 13th straight road win against AFC West opponents.

Mahomes completed 27 of 44 passes for 270 yards with two TD passes for Travis Kelce in the first quarter and Jerick McKinnon in the third. The Kansas City QB also rushed 54 yards from nine carries.

The Broncos, who will finish last in the AFC West with a 7-10 record, were difficult to shake all game, with QB Drew Lock rushing two touchdowns, while running back Gordon scored a 47-yard TD to put them up 20-17 in the third.

The Chiefs found the match-winning play in the fourth quarter as the Broncos closed the nine-yard line after a 10-play drive with Ingram forcing the error and Lock unable to tackle Bolton.
