Amidst a snowy backdrop in Buffalo, Josh Allen delivered a career-defining performance, leading the Bills to a resounding 35-10 victory over the San Francisco 49ers. This win secured the AFC East division title for the Bills for the fifth consecutive season. Fresh off his engagement announcement, Allen showcased his exceptional skills, overcoming challenging weather conditions to orchestrate a masterful offensive display.

Allen contributed to the scoring in multiple ways, starting with a 7-yard touchdown pass to Mack Hollins before halftime. The Bills entered the locker room with a commanding 21-3 lead. In the third quarter, Allen added a unique touchdown to his stat line. After receiving a lateral pass from Amari Cooper, Allen rushed into the end zone, marking a rare receiving touchdown for a quarterback. He finished the game with zero official receptions but seven receiving yards and a touchdown.

Allen capped off his remarkable performance with an 8-yard rushing touchdown in the fourth quarter, solidifying the Bills' victory. He became the first NFL quarterback since the merger to record a passing, rushing, and receiving touchdown in a single game. Allen's final stats included 148 passing yards and 18 rushing yards.

The Bills' running game also played a significant role in their success. James Cook had a standout performance with a 65-yard touchdown run and 107 total rushing yards. Ray Davis added a 5-yard rushing touchdown and contributed 59 rushing yards. The 49ers struggled to contain the Bills' potent offense, particularly in the snowy conditions. San Francisco's star running back, Christian McCaffrey, suffered a knee injury in the first half and did not return.

49ers quarterback Brock Purdy faced constant pressure from the Bills' defense and finished with just 94 passing yards. Isaac Guerendo scored the 49ers' only touchdown. With this win, the Bills extended their winning streak to seven games, improving their record to 10-2. Meanwhile, the 49ers fell to 5-7, facing a challenging path ahead.
