Seahawks Crush Chiefs 20–3: How Seattle Silenced Mahomes and Ended Kansas City’s Unbeaten Start

SEATTLE — October 25, 2026. The Seattle Seahawks handed the previously unbeaten Kansas City Chiefs their first defeat of the NFL season on Sunday night, winning 20–3 at Lumen Field. The most striking number was not the 17-point margin but Kansas City’s three points: Seattle kept Patrick Mahomes and an offense that entered the game 5–0 out of the end zone.

Seattle’s offense provided the separation, but its defense established the terms. According to Reuters’ October 26 game report, the Seahawks outgained Kansas City 410 yards to 213. Mahomes completed 19 of 33 passes for 165 yards and threw an interception. That combination illustrates why the result was more than a single stalled red-zone drive: Kansas City struggled to move the ball consistently.

The decisive difference: Explosive receiving and a defense that refused to bend

Jaxon Smith-Njigba caught nine passes for 150 yards and a touchdown. His 28-yard scoring catch from Sam Darnold helped Seattle establish a 10–0 halftime lead; the Seahawks’ official clip documents that precise play. Darnold finished 20-of-28 for 257 yards, a touchdown and an interception, according to Reuters.

Seattle’s approach did not depend on a relentless scoring barrage. Jason Myers added field goals, and Emanuel Wilson’s 21-yard fourth-quarter touchdown run finally put the game beyond reach. Kansas City’s only points came on Harrison Butker’s 50-yard field goal late in the third quarter. Seattle’s official game clips also show Ty Okada intercepting Mahomes and Derick Hall forcing a fumble. Those plays are important context: they show how pressure and disruption complemented the Seahawks’ offensive efficiency.

Why this result matters

Kansas City arrived with an unbeaten record and a reputation for recovering from difficult stretches. Seattle’s win challenged that formula by denying Mahomes easy possessions and forcing the Chiefs to chase a deficit without the explosive passing plays they needed. The result moves Seattle to 4–3 and drops Kansas City to 5–1, according to Reuters. It does not settle either team’s season, but it offers a concrete blueprint for opponents: limit early scoring opportunities, make the Chiefs sustain drives and convert defensive disruption into field position.
