In a crucial Week 12 matchup, the San Francisco 49ers emerged victorious, defeating the Seattle Seahawks 21-10. With playoff implications on the line, the 49ers solidified their standing in the division, while the Seahawks faced a tough setback in their pursuit of postseason contention. Brock Purdy led the 49ers offense with precision, throwing for two touchdowns and 164 yards, effectively managing the game. Javonte Williams was a key contributor on the ground, racking up 76 rushing yards, while Purdy's passing game found targets like Deebo Samuel, keeping the Seahawks' defense on its heels. Sam Darnold, despite his 188 passing yards and A.J. Barner's impressive 72 receiving yards, struggled to find the end zone. The 49ers defense played a pivotal role in the game, notably through Alfred Collins, who recorded 2.5 sacks, applying constant pressure on Darnold. Jaylon Johnson’s interception further stifled Seattle's efforts, swinging momentum in favor of San Francisco. The turning point came in the second quarter when the 49ers turned a pivotal stop into a touchdown drive, effectively taking control of the game and never looking back.
