In a compelling Week 4 matchup, the San Francisco 49ers topped the Denver Broncos with a final score of 35-20, solidifying their strong start to the 2026 season. The victory not only boosts San Francisco's confidence but also keeps them in the playoff conversation early in the year. Brock Purdy was the standout performer for the 49ers, throwing for 221 yards and four touchdowns, showcasing his precision and poise in the pocket. Christian McCaffrey added a powerful rushing presence, accumulating 129 yards on the ground, which helped to control the tempo of the game. For the Broncos, Jaylen Waddle led the receiving corps with 65 yards, but it was not enough to match the 49ers' offensive firepower. Defensively, the 49ers made crucial plays that swung the momentum their way, particularly with Renardo Green's interception, which halted a potential scoring drive for Denver. Alfred Collins' sack also disrupted the Broncos' rhythm, creating pressure that forced them into uncomfortable situations. The turning point came late in the second quarter when Purdy connected with a touchdown pass that extended the lead, leaving Denver scrambling to keep up.
