The San Francisco 49ers emerged victorious over the Seattle Seahawks with a commanding final score of 33-7 in Week 12 of the 2026 season. With playoff implications on the line, the 49ers solidified their standing in the division, showcasing their dominance against a rival team. Brock Purdy was the standout performer for San Francisco, throwing for 342 yards and three touchdowns, effectively leading the offense throughout the game. Christian McCaffrey also had a significant impact, racking up 127 receiving yards, providing Purdy with a reliable target. The combination of their efforts ensured that the 49ers maintained control and consistently found ways to exploit Seattle's defense. Defensively, San Francisco made key plays that stifled Seattle's offensive rhythm. While the Seahawks' Jadarian Price managed to rush for 61 yards, the 49ers' defense forced critical turnovers, including an interception by Marques Sigle. The turning point came when Purdy connected with McCaffrey for a touchdown just before halftime, swinging momentum entirely in favor of San Francisco and leaving the Seahawks struggling to catch up.
