Unbeaten 49ers face the Denver Broncos in a high-stakes pass-rush test.

San Francisco has lost yardage on just four plays from scrimmage through three games—the fewest through three games since at least 2000—and has scored touchdowns on nearly half of its possessions.
Denver has recorded 139 sacks since the start of the 2024 season, 27 more than any other team in that span, making its pass rush a particularly demanding test for San Francisco’s sack-free start.
Beyond the players noted in the summary, linebacker Dre Greenlaw is questionable with a quad contusion, and rookie linebacker Jaden Dugger is a game-time decision after injuring his shoulder in practice.
Mike Evans has caught 12 passes for 137 yards and two touchdowns in his first three appearances with San Francisco; Purdy has a 139.8 passer rating when targeting him.
The unbeaten San Francisco 49ers bring the NFL's most efficient offense to Denver on Sunday, seeking to extend their perfect start against a Broncos defense built to stop exactly what makes San Francisco dangerous: the pass rush. NFL.com reports Brock Purdy leads the league in passer rating while avoiding sacks entirely through three games—a historic start that Denver's league-leading pass rush will immediately test.
San Francisco's 3-0 record masks an even more dominant reality: the 49ers have lost yardage on just four plays from scrimmage all season, the fewest through three games since at least 2000, ESPN noted. Denver enters at 2-1 but has compiled 139 sacks since the start of 2024—27 more than any other team—making this matchup a collision between San Francisco's historic offensive efficiency and Denver's elite pressure machine.
Brock Purdy has thrown nine touchdowns and one interception while posting a 139.8 passer rating, The Athletic reported. The 49ers quarterback has not taken a single sack through three games—a vulnerability the Broncos' pass rush will attack relentlessly. Denver's defense has recorded 139 sacks since 2024 began, a league-leading total that sets up a critical test of San Francisco's offensive line.
San Francisco has scored touchdowns on nearly half of its possessions while avoiding turnovers for 11 straight quarters, NFL.com confirmed. This efficiency cannot continue if Purdy hits the ground. Denver's pass rush—the NFL's most lethal—will pressure him early and often, forcing quick decisions that could break San Francisco's sack-free streak.
While the Broncos excel at generating pressure, their run defense remains vulnerable—an opening the 49ers should attack with Christian McCaffrey. San Francisco's ground game has been a core component of its balanced attack, and Denver's defensive weakness presents an opportunity to control time of possession and limit the Broncos' offensive chances.
McCaffrey carries a 49ers team that averages 32.7 points per game, per Sports Illustrated. If Denver focuses resources on stopping the pass rush, the Broncos risk giving up big runs. San Francisco will likely lean on the ground early to establish rhythm and protect Purdy from Denver's elite pass rush.
Wide receiver Mike Evans, acquired recently, has caught 12 passes for 137 yards and two touchdowns in his first three games with San Francisco, 49ers.com reported. His connection with Purdy has been immediate and productive—the quarterback posts a 139.8 rating when targeting him. But Evans is listed as questionable with a rib injury, threatening his availability against Denver.
Beyond Evans, the 49ers face multiple defensive absences: linebacker Dre Greenlaw is questionable with a quad contusion, and rookie Jaden Dugger is a game-time decision after a shoulder injury in practice. Nick Bosa and other key pass rushers are also ruled out or uncertain. Denver's offense will have opportunities to exploit San Francisco's thin defense.
Denver acquired wide receiver Jaylen Waddle from Miami to bolster its passing attack, Star-Telegram reported. The Broncos need offensive firepower to keep pace with San Francisco's 32.7 points per game average. Waddle gives Denver a vertical threat to attack the 49ers' secondary, though the Broncos must first slow Purdy to stay in the game.
Waddle cannot be merely a decoy against San Francisco's stout defense. The Broncos must move the ball quickly and score early to avoid falling behind to a 49ers team that rarely punts. Denver's pass rush is the team's best chance to disrupt San Francisco's rhythm before Waddle and the offense take over.
