Four Key Takeaways From the 49ers’ Gritty 24-14 Victory Over the Broncos

The San Francisco 49ers advanced to a perfect 4-0 on the 2026 season following Sunday's 24-14 win over the Denver Broncos. It was anything but a clean, routine afternoon at Levi’s Stadium. The game featured a blocked field goal, a fourth-down stall, and an early timeout burned due to personnel confusion.

Yet, as the clock hit zero, Kyle Shanahan’s squad once again found a way to stand tall. Here are the four biggest takeaways from Sunday's cross-conference victory.

Four weeks into the regular season, San Francisco’s roster looks like a medical triage unit. The pass-catching room is missing its depth, the secondary is shuffling safety combinations mid-quarter, and the defensive line has been completely gutted by injuries.

Despite the constant roster turnover, the 49ers refuse to flinch. Good football teams make excuses, but elite organizations adapt. Whether it's special teams forcing a timely third-quarter fumble, a backup stepping into a starter’s role without missing a beat, or veterans battling through cracked ribs, the 49ers have spent four consecutive weeks demonstrating that their winning culture runs deeper than any individual starter.

If there’s an unsung hero through the first month of the season, it’s defensive coordinator Raheem Morris. Against a high-powered Denver offense, Morris was tasked with calling a game using a defensive line that featured almost no available players from the initial 53-man roster.

Despite operating without elite edge speed, Morris dialed up creative front-seven looks and blitz packages that generated 16 pressures on Bo Nix. By deploying linebackers Dre Greenlaw and Fred Warner on aggressive run-blitzes and leaning on a rotated secondary, Morris held the Broncos to just six points through the game's first 56 minutes. Shutting down one of the league's top-tier offenses with depth-chart reinforcements is an early-season masterclass in play-calling and player development.

While much attention is focused on Brock Purdy’s 11-touchdown start to the year, the engine making the entire offense hum is the five men up front.

Through four complete games in 2026, the 49ers' offensive line has not surrendered a single sack on Purdy. Even as Denver’s front seven brought exotic pressure looks, Trent Williams and the interior line kept Purdy clean when it mattered most. That pass protection allowed Purdy to stay patient in the pocket and eventually seal the game with a 56-yard touchdown strike to George Kittle late in the fourth quarter.

In a game defined by tough defense and field position, special teams delivered the turning point. After a low-scoring first half ended with a blocked 49ers field goal, the third quarter called for a splash play. Siran Neal provided exactly that, stripping Broncos returner Marvin Mims Jr. on a 61-yard punt and recovering the fumble in plus territory. Nine plays later, Purdy found Deebo Samuel for a touchdown to give San Francisco its first lead. In tight, physical football games, winning the hidden yardage on special teams is often the difference between 3-1 and 4-0.
