Kansas City's difficulty in tight contests persists following their defeat against the Broncos, impacting their record in one-score games.

In 2024, some proposed that the Kansas City Chiefs were fueled by infernal sorcery. Should that have been accurate, the enchantment appears to have dissipated by 2025.

Kansas City's path to the Super Bowl was significantly influenced by their success in tight contests. The Chiefs didn't merely perform well in games decided by one score; they were flawless, achieving an 11-0 record during the regular season, which propelled them to their third consecutive Super Bowl berth.

While luck played a role in some victories, the overwhelming majority stemmed from excellent performance during the game's closing stages. Led by Patrick Mahomes and with Andy Reid directing from the sideline, Kansas City clearly demonstrated composure as a key asset.

As of 2025, this hasn't been the situation. The Chiefs have lost several close games, ending their record-setting streak in such contests.

Regarding Kansas City's inconsistent performances in close contests, here's the essential information.

The Chiefs played in one-score games in 2025.

Here are all of the Chiefs' one-score games this season.

The Chiefs' performance in games decided by a single score during the 2025 season.

Following their loss to the Jaguars Monday evening, the Chiefs' record in one-score games this season is now 0-3 . The dominance they exhibited during their record-setting streak in these close matches appears to have disappeared, giving way to an inconsistent performance across all three phases of the game.

This season, we're examining the Chiefs' results in games decided by a single score, starting with their loss in the season opener against the Los Angeles Chargers and continuing through their Week 5 collapse against the Jacksonville Jaguars.

Week 1 vs. Chargers

Kansas City's remarkable 2024 record in tight contests has concluded. In the opening match of the Chiefs' 2025 campaign, they lost to the Chargers 27-21.

This marked their initial defeat in a close contest by a single score since Christmas Day in 2023, a 20-14 loss against the Raiders during Week 17. Prior to this, Kansas City had secured wins in all other games decided by eight points or fewer.

This season, in their pursuit of ending the Chiefs' AFC West reign, Jim Harbaugh's team secured a crucial victory, bolstered by Justin Herbert's 318-yard performance.

Week 2 vs. Eagles

Kansas City's Week 2 loss to the Philadelphia Eagles mirrored their previous week's outcome, as the Chiefs again suffered a narrow defeat, this time by a score of 20-17.

It's understandable to lose to a team as skilled as Philadelphia. However, the way the loss occurred, with Patrick Mahomes only completing 16 of 29 passes for 173 yards, a single touchdown, and one interception, left Chiefs fans feeling disappointed.

Week 5 vs. Jaguars

In the initial quarter, the Chiefs appeared prepared to counter the Jaguars' challenge, establishing a 14-point lead against their AFC South opponent during Week 5.

The lead evaporated as Trevor Lawrence orchestrated a series of scoring drives. Jacksonville's quarterback fumbled and fell in the closing minutes of the fourth quarter. However, he recovered, created an opening, and stealthily reached the end zone. This touchdown sealed the game, with The Jaguars securing a 31-28 win against their favored opponents. This victory held historical weight for Jacksonville, marking their first triumph over the Chiefs since 2009.

The game also became infamous for The Kansas City Chiefs, marking their first loss in 23 contests where they had held a lead of at least two touchdowns.

Week 11 vs. Bills

The Chiefs reignited their competition with the Bills. As typically happens during the regular season, Kansas City failed to secure a win against their AFC East opponent, losing 28-21 to Sean McDermott's team.

Mahomes had a rough outing against Buffalo's defense, throwing an interception during the game. Although the outcome hinged on a single possession, Buffalo largely dictated the pace of the match.

Week 12 vs. Broncos

Until late in the fourth quarter, Kansas City seemed poised to win its Week 12 matchup against the Broncos. However, Bo Nix and Denver then drove down the field, scoring two field goals, with the last one securing a significant win for The Broncos.
