Patrick Mahomes endured an unprecedented offensive collapse as the Kansas City Chiefs suffered their first defeat of the 2026 NFL season. Seahawks dominated Kansas City 20-3 on Sunday night, exposing problems that had been hidden during the team's unbeaten start.
The loss marked a historic low for Mahomes, whose offense failed to reach the red zone even once.
According to ESPN insider Adam Schefter, Kansas City had reached the red zone in each of Mahomes' previous 152 starts. That streak included both regular-season and playoff appearances.
Sunday's game at Lumen Field ended that remarkable run, highlighting Seattle's suffocating defensive performance.
Mahomes completed 19 of 33 passes for just 165 yards and one interception. He failed to throw a touchdown as Kansas City struggled to sustain drives.
The Chiefs managed only 213 total yards and 11 first downs. They also converted just three of their 11 third-down opportunities.
Running back Kenneth Walker III endured a difficult reunion with his former team. After his historic early-season rushing performances, Walker managed just 36 yards on 14 carries.
Seattle's defense consistently disrupted Kansas City's rhythm, preventing Mahomes from finding answers throughout the contest.
Meanwhile, Seahawks receiver Jaxon Smith-Njigba recorded nine catches for 150 yards and a touchdown. His performance helped Seattle improve to 4-3.
