In a decisive Week 4 matchup, the San Francisco 49ers beat the Denver Broncos 21-7, solidifying their position in the early season standings. With both teams looking to establish momentum, the 49ers showcased their balanced attack and strong defense to secure the victory. Bo Nix led the Broncos with 132 passing yards and a touchdown, but it was the 49ers' ability to control the ground that made the difference. Christian McCaffrey was the standout performer on the ground for San Francisco, rushing for 44 yards, while Courtland Sutton topped the receiving charts for Denver with 66 yards. Despite the Broncos' efforts, they struggled to keep pace with the 49ers' offensive efficiency. Defensively, the 49ers put on a clinic, with Nick Bosa leading the charge with 1.5 sacks and Renardo Green snagging an interception. The turning point came late in the second quarter when Green's interception halted a promising Broncos drive, allowing San Francisco to extend their lead. With key stops and pressure on the quarterback, the 49ers' defense was crucial in maintaining control throughout the game.
