In an exhilarating Week 4 matchup, the San Francisco 49ers outlasted the Denver Broncos with a final score of 42-35, securing a crucial victory in the 2026 season. Both teams battled fiercely, but the 49ers' high-powered offense and opportunistic defense ultimately made the difference in this tightly contested game. Christian McCaffrey was the standout performer for San Francisco, dominating both on the ground and through the air. He rushed for a staggering 195 yards and added 81 receiving yards, scoring vital touchdowns that kept the 49ers in the lead. On the other side, Broncos quarterback Bo Nix had a solid game, throwing for 221 yards and two touchdowns, but it wasn’t enough to overcome San Francisco’s offensive firepower. Defensively, Chuck Clark was a game-changer for the 49ers, recording two interceptions that shifted momentum at critical moments. The Broncos' defense struggled to contain McCaffrey and could not capitalize on Nik Bonitto’s two sacks, which put pressure on the 49ers’ offense. The turning point came late in the fourth quarter when Clark's second interception thwarted a Denver drive, sealing the game for San Francisco and securing their place in the standings.
