In a decisive clash in Week 4 of the 2026 season, the San Francisco 49ers secured a solid 27-10 victory over the Denver Broncos. This win keeps the 49ers on track as they aim for a strong playoff push, while the Broncos look to regroup after a disappointing performance. Offensively, Brock Purdy led the 49ers with a steady performance, throwing for one touchdown, while Bo Nix of the Broncos racked up 206 passing yards. RJ Harvey shined on the ground for Denver, rushing for an impressive 110 yards, and Evan Engram was a reliable target, finishing with 72 receiving yards. However, it was the 49ers’ ability to capitalize on scoring opportunities that ultimately set them apart. Defensively, San Francisco's Nick Bosa made his presence felt, recording a critical sack that helped disrupt the Broncos' offensive rhythm. The turning point came in the second quarter when the 49ers’ defense forced a turnover, allowing them to extend their lead and control the game. With Alex Singleton leading the charge for Denver with seven tackles, their defense fought hard, but it wasn't enough to overcome the 49ers’ balanced attack and defensive pressure.
