SEATTLE (Interstat) — In a stunning and decisive display of dominance, the Seattle Seahawks extinguished the San Francisco 49ers’ season with a 41-6 rout in an NFC playoff game Saturday at a raucous Lumen Field. A crowd of 68,579 witnessed the Seahawks, who had narrowly edged the 49ers just two weeks prior, deliver a comprehensive beatdown from the opening kickoff, advancing to the next round while handing their division rivals their most lopsided defeat of the year.

The tone was set in a catastrophic opening 15 seconds for San Francisco. Seattle’s Rashid Shaheed fielded the opening kickoff at his own 5-yard line and sliced through the 49ers’ coverage unit for a 95-yard touchdown return. The score, coupled with a penalty on the kicker Eddy Pineiro, gave Seattle a lead it would never remotely relinquish. The early special teams disaster seemed to disorient the visiting 49ers, who finished the season 13-6, and electrified the home squad, which improved to 15-3.

From there, the Seahawks’ defense took over, completely stifling a San Francisco offense that managed only a pair of Eddy Pineiro field goals in the second quarter. Quarterback Brock Purdy was under constant duress, sacked three times and harassed into an inefficient performance, completing 15 of 27 passes for 140 yards. His primary connection was to tight end Jake Tonges, who caught five passes for 59 yards, but the 49ers’ star runner Christian McCaffrey was held to 35 yards on 11 carries. The 49ers’ deepest penetration was to the Seattle 22-yard line, resulting in their first field goal.

Conversely, Seattle’s offense, led efficiently by quarterback Sam Darnold, operated with precision. Darnold completed 12 of 17 passes for 124 yards and a touchdown, but the engine of the attack was unequivocally running back Kenneth Walker III. Walker delivered a tour de force, galloping for 116 yards on 19 carries and scoring three touchdowns. He added three receptions for 29 yards, proving to be an unstoppable force. His first-half touchdown, a 7-yard run with 31 seconds left before the break, pushed the lead to 24-6 and effectively buried any lingering 49ers’ hopes.

The Seahawks’ defense was a swarming, opportunistic unit. Linebacker Ernest Jones IV intercepted a Purdy pass intended for Luke Farrell in the third quarter, snuffing out a potential San Francisco drive. The tackling was relentless, with linebackers Drake Thomas and Ernest Jones IV each recording six tackles, while cornerback Devon Witherspoon led all players with seven. The defensive front, featuring Leonard Williams and DeMarcus Lawrence who each recorded a sack, controlled the line of scrimmage throughout.

After taking a 24-6 lead into halftime, Seattle removed all doubt in the third quarter. They methodically marched 66 yards on their opening second-half drive, culminating in a 24-yard Jason Myers field goal. Following Jones’ interception, the Seahawks put the game completely out of reach with another sustained drive, finished by Walker’s second touchdown, a 15-yard scamper that made it 34-6. He would add a third touchdown early in the fourth quarter to cap the scoring.

The most important sequence of the game was its very first play. Shaheed’s instant touchdown return provided an immediate and overwhelming emotional and scoreboard advantage to the home team. It placed the 49ers, a team that had struggled offensively in a 13-3 loss to this same Seattle team two weeks earlier, into an immediate and deep hole on the road in a playoff atmosphere. That opening shockwave set the entire trajectory of the contest, allowing Seattle’s defense to play aggressively with a lead and its offense to lean on Walker without pressure. The 49ers never recovered from that initial jolt, and the game was effectively defined in its first 15 seconds.

The victory was a emphatic statement for a Seahawks team that had been projected by Interstat’s game simulator to win 30-24, with their ELO system giving them a 79.2 percent probability. They far exceeded that margin, showcasing a complete performance that blended explosive special teams, a physically punishing ground game, and an impenetrable defense. For the 49ers, the loss marks a bitterly disappointing end to a season that included a playoff win in Philadelphia just six days earlier, but ultimately found them utterly overmatched by their fiercest division foe on the NFL’s postseason stage.
