In a hard-fought battle, the San Francisco 49ers secured a 20-10 victory over the Denver Broncos in Week 4 of the 2026 season. With both teams looking to gain momentum early in the season, the 49ers' win solidifies their position in the playoff hunt while the Broncos face more questions heading into the next game. Brock Purdy was the standout performer for the 49ers, throwing for 197 yards and two touchdowns, showcasing his ability to command the offense effectively. Christian McCaffrey was a force on the ground, racking up 121 rushing yards and keeping the Broncos' defense on its heels throughout the game. Troy Franklin led the Broncos in receiving with 99 yards, but it wasn't enough to spark a comeback. Defensively, the game was defined by the 49ers' ability to stifle the Broncos' offense, forcing them into tough situations. Denver's defense had bright spots, with Zach Allen recording 1.5 sacks and Talanoa Hufanga picking off two passes, but it was the 49ers' timely stops that turned the tide. The turning point came in the second half when San Francisco's defense held the Broncos to just a field goal, allowing their offense to extend the lead and ultimately seal the win.
