In a game they probably shouldn’t have won, the Broncos beat the Chiefs with a goal-line stand in the final seconds.

Denver stopped Kansas City four times inside the 10-yard line, winning 28-24 for Sean Payton’s 200th career victory, including the postseason. The Broncos lead the AFC West at 6-2, while the Chiefs fell to 5-2 with a second consecutive loss.

Denver trailed 24-13 in the fourth quarter before scoring 15 consecutive points for its fourth comeback win of the season.

The Chiefs uncharacteristically fell apart when it mattered most.

They had a chance to pad their lead, but Harrison Butker missed a 54-yard field goal wide right with 2:31 remaining. It came after Alex Singleton sacked Patrick Mahomes for 6-yard loss.

Butker is in danger of losing his job after the Chiefs signed Justin Tucker to the practice squad last week. The 10-year veteran has missed 6 of 17 field-goal attempts this season, including two misses in last week’s loss to the Seahawks.

Two plays, 56 yards and 35 seconds later, the Broncos led for the first time. Jonah Coleman had a 51-yard catch-and-run before a 5-yard touchdown run. The Broncos led 28-24 with 1:56 left.

Emmett Johnson, the star for the Chiefs on Sunday, returned the kickoff 44 yards to the Kansas City 44, and two plays later, Mahomes found Travis Kelce for a 32-yard gain to the Denver 18.

The Chiefs had first-and-goal at the 4 with 35 seconds left. Kenneth Walker ran for 3 yards to the 1 before Patrick Surtain tackled him; Mahomes threw incomplete; and Walker was stopped for no gain by safety JL Skinner. That set up a final play with four seconds left, and after a false start, Malcolm Roach sacked Mahomes to end the game.

The Chiefs outgained the Broncos 399 to 294 as Mahomes went 30-of-41 for 321 yards and three touchdowns. Johnson caught five passes for 128 yards and a touchdown and had a 15-yard run. Kelce added five catches for 67 yards.

Bo Nix was 20-of-32 for 222 yards and two touchdowns, going 5-of-6 for 84 yards and a touchdown in the fourth quarter. Coleman had 11 carries for 41 yards and a touchdown and four catches for 63 yards.
