The Seattle Seahawks topped the San Francisco 49ers with a convincing 34-21 victory in Week 12 of the 2026 season. With playoff implications on the line, Seattle solidified their position as a contender, delivering a strong performance on the road against a divisional rival. Seahawks quarterback Taylen Green led the charge, throwing for 303 yards and showcasing his precision with the passing game. He connected with Ja'Kobi Lane, who made a significant impact with 127 receiving yards, proving to be a reliable target in crucial moments. On the ground, Mike Washington Jr. contributed with 74 rushing yards, providing balance to the Seahawks' offensive attack. Defensively, while the 49ers struggled to generate pressure with only half a sack credited to Roquan Smith, they did have standout performances, including Donte Jackson's six tackles. However, Seattle's ability to maintain offensive momentum, particularly in the second half, ultimately shifted the game's dynamic. The turning point came in the third quarter when the Seahawks scored two quick touchdowns, putting the 49ers in a difficult position they couldn't recover from.
