Match Overview Table

Core Match Statistics Overview

Third Down Efficiency

San Francisco converted over half of its third down attempts, extending drives that kept Seattle’s offense off the field. Seattle’s inability to stay on the field on third down forced its defense into unfavorable situations repeatedly.

The 49ers converted 4 of 6 third downs in the second half, including a critical 3rd-and-8 completion to George Kittle that set up the go-ahead field goal.

Seattle managed just 2 of 5 third down conversions after halftime, with two drives ending in punts.

Turnover Margin

San Francisco’s defense intercepted Darnold twice in the second half, both leading to scoring drives.

Seattle’s one takeaway resulted in zero points after a failed fourth-down attempt.

San Francisco 49ers Player Statistics

Brock Purdy, QB

Purdy delivered his fourth game this season with three or more touchdown passes, cementing his early MVP case. His third-down conversion to Kittle in the final two minutes demonstrated the poise that has defined San Francisco’s unbeaten run.

Christian McCaffrey, RB

McCaffrey’s versatility kept Seattle’s defense guessing, as he converted multiple third downs as both a runner and receiver. His 4-yard touchdown run in the first quarter set the tone for San Francisco’s balanced attack.

George Kittle, TE

Kittle’s 28-yard catch on third-and-8 in the final two minutes was the game’s most consequential non-scoring play. He consistently found soft spots in Seattle’s zone coverage, particularly on crossing routes.

Nick Bosa, DE

Bosa’s second-half pressure forced Darnold into both of his interceptions. His strip-sack attempt in the third quarter nearly resulted in a turnover, and his presence altered Seattle’s protection schemes throughout.

Seattle Seahawks Player Statistics

Sam Darnold, QB

Darnold showed flashes of brilliance, particularly on his 22-yard touchdown to Metcalf, but his two second-half interceptions proved costly. Both picks came under duress from San Francisco’s pass rush.

Kenneth Walker III, RB

Walker ran hard between the tackles, keeping Seattle’s offense ahead of the chains. His 1-yard touchdown plunge in the third quarter briefly gave Seattle momentum.

DK Metcalf, WR

Metcalf’s size and speed created mismatches, but San Francisco’s corners limited his yards after catch. His 22-yard touchdown reception showcased his ability to win contested catches.

Jaxon Smith-Njigba, WR

Smith-Njigba’s 38-yard grab in the first quarter was Seattle’s longest play of the game. He consistently found space in the intermediate passing game, though Darnold missed him on a potential big play in the fourth quarter.

Statistical Leaders Summary Table

Why the 49ers Won

Third Down Conversions

San Francisco’s ability to extend drives on third down kept Seattle’s offense on the sideline. The 49ers converted 53.8% of their third downs, including the game-clinching 28-yard completion to Kittle.

Red Zone Efficiency

The 49ers scored touchdowns on three of four red zone possessions, while Seattle managed just two touchdowns in four trips. This four-point differential ultimately decided the game.

Pass Rush Production

San Francisco’s defensive front generated consistent pressure without blitzing, allowing seven defenders to drop into coverage. The 49ers sacked Darnold three times and hit him on eight additional occasions.

Ball Control in Critical Moments

Purdy’s decision-making in the final five minutes contrasted sharply with Darnold’s. While Purdy completed three of four passes for 47 yards on the game-winning drive, Darnold’s final possession ended with an incompletion on fourth down.

Why the Seahawks Lost

Turnover Differential

Seattle’s two interceptions directly led to ten San Francisco points. Darnold’s first interception came on a forced throw into double coverage, and his second resulted from miscommunication with Metcalf on a hot route.

Inability to Contain Kittle

Seattle’s linebackers struggled in coverage against Kittle, who caught seven passes for 94 yards. The Seahawks allowed five receptions of 15+ yards to tight ends, a season-long problem that San Francisco exploited.

Red Zone Play Calling

Seattle’s red zone offense became predictable, relying on fade routes to Metcalf that San Francisco’s corners defended effectively. The Seahawks ran the ball just three times inside the 20, failing to establish balance.
