SEATTLE (AP) Jaxon Smith-Njigba caught nine passes for 150 yards and a touchdown, and the Seattle Seahawks handed the Kansas City Chiefs their first loss of the season, 20-3 on Sunday night.

Sam Darnold threw for 257 yards and a score for the Seahawks (4-3), who snapped a two-game skid. Emanuel Wilson had 24 carries for 100 yards and a TD.

Patrick Mahomes struggled, throwing for 165 yards with an interception for the Chiefs (5-1). Kenneth Walker III, the Super Bowl MVP for the Seahawks last season before signing with the Chiefs in the offseason, was held to 36 yards on 14 carries.

Walker entered the night averaging a league-leading 133 yards per game, but the Seahawks shut him down, along with the rest of Kansas City's offense. The Chiefs had 213 total yards, 50 on the ground.

Seattle has not allowed a 100-yard rusher in 36 games, the league’s longest current streak.

The only bright spot for Kansas City's offense was a milestone for Travis Kelce, who had four receptions to reach 1,104 for his career, moving past Marvin Harrison and Cris Carter for fifth in NFL history.

After Darnold hit Smith-Njigba for a 33-yard gain early in the second quarter to get the Seahawks in the red zone, Jason Myers kicked a 25-yard field goal for a 3-0 lead.

On the next series, Ty Okada intercepted Mahomes on a pass intended for Jalen Royals. Seattle's ensuing drive was kept alive by Darnold's 7-yard scramble. He then connected with Smith-Njigba for a 28-yard touchdown to put Seattle up 10-0 with 1:44 left in the first half.

Another 28-yard pass from Darnold to Smith-Njigba got the Seahawks to the Kansas City 1 in the closing seconds of the half, but Darnold was intercepted by Nohl Williams in the back of the end zone. Williams returned the pick 64 yards, but Harrison Butker's 58-yard field goal attempt fell short as time expired.

Myers made a 35-yard field goal to extend Seattle's lead to 13-0. Before the third quarter was over, the Chiefs drove to the Seattle 30, but Mahomes fumbled on third down and Kansas City had to settle for Butker's 50-yard field goal.

Mahomes found Kelce for a 19-yard catch early in the fourth quarter, but the Chiefs came away with no points when Butker missed a 45-yard field goal attempt wide right. Butker has missed 10 field goals since the start of last season.

The Seahawks pushed their lead to 20-3 on Wilson's 21-yard scoring run with 3:47 left.

The Seahawks moved running back Zach Charbonnet to the active roster this week, but he was ruled out for the game. Charbonnet rushed for 730 yards and 12 touchdowns for the Seahawks last season before he tore an ACL.

The Chiefs were without receiver Rashee Rice, who missed his third straight game with a hamstring injury, and starting tackle Jaylon Moore, who is in the concussion protocol.

Seahawks receiver Rashid Shaheed left early in the second half with a knee injury. He did not return. Tackle Charles Cross left in the fourth quarter with an ankle injury.

The Chiefs visit the Denver Broncos next Sunday.

The Seahawks host the Chicago Bears on Monday, Nov. 2
