Sam Darnold and the Seattle Seahawks handed Patrick Mahomes and the Kansas City Chiefs their first loss of the season with a 20-3 victory at home on Sunday night.

With the 12th Man behind them, Seattle entered the matchup as a 3-point favorite over Kansas City, according to FanDuelSportsbook .

It was an ugly game for the Chiefs' offense, with dropped passes, turnovers, and missed opportunities at every turn.

Mahomes was held without a touchdown, marking back-to-back games in which the former two-time NFL MVP failed to find the end zone.

Not only was Mahomes held without a touchdown, but Kansas City failed to reach the red zone all game, marking the first time in Mahomes' career that the Chiefs were held out of the red zone.

The Chiefs fell to 5-1 on the season, while Seattle snapped a two-game losing streak to improve to 4-3.

With the Chiefs' loss and the San Francisco 49ers falling earlier Sunday, the 6-0 Minnesota Vikings are the only undefeated team remaining in the 2026 NFL season.

After a scoreless first quarter, the Seahawks took a 10-0 lead into halftime behind a field goal and a 28-yard touchdown pass from Darnold to Jaxon Smith-Njigba.

Darnold threw an interception before halftime, but Kansas City's Harrison Butker missed a 58-yard field goal on the ensuing possession, negating the turnover.

Meanwhile, Mahomes and the Chiefs struggled offensively, punting on three possessions and throwing an interception as they entered halftime without a point and just 92 total yards of offense.

Both teams added field goals in the third quarter, with Butker nailing a 50-yarder to put the Chiefs on the board for the first time with 1:42 remaining in the quarter.

With a chance to cut the deficit to one score, Butker missed his second field goal of the game, giving the ball back to Seattle.

The Seahawks ran down the clock and capped the drive with a 21-yard rushing touchdown by Emanuel Wilson to extend their lead, before sealing the win with a defensive stop on downs.

The Chiefs will remain on the road to face the Denver Broncos next Sunday at 4:25 p.m. ET, while the Seahawks will take on the Chicago Bears next Monday at 8:15 p.m. ET.
