Seahawks Defense Holds Mahomes and Walker to Season Lows in 20-3 Win Over Chiefs

What happened
The Seattle Seahawks handed the Kansas City Chiefs their first defeat of the 2026 season with a 20-3 defensive rout at Lumen Field.
The Context
* A dominant defensive clinic: Seattle prevented Kansas City from entering the red zone entirely, holding Patrick Mahomes to 165 passing yards, zero touchdowns, and one interception. * Neutralizing the league's top rusher: Former Seahawks running back Kenneth Walker III entered leading the NFL in rushing yards but was restricted to 36 yards on 14 carries with no run longer than seven yards. * Balanced offensive control: Seattle quarterback Sam Darnold threw for 257 yards, receiver Jaxon Smith-Njigba logged 150 yards on nine catches, and the ground game generated 153 total rushing yards across 41 carries.
The Number
— The total points scored by Kansas City, tying the career-low output for any start by Patrick Mahomes and marking Seattle's stingiest defensive showing of the year.
Takeaway
Seattle advances to 4-3 to challenge the NFC West hierarchy, while Kansas City must retool its offensive schemes before facing divisional opponents.
