The San Francisco 49ers turned Levi's Stadium into a track meet Sunday, running past the Denver Broncos 53-31 in a Week 4 shootout that never lacked for scoreboard operators. Denver moved the ball with real force, but the Niners answered every push with one of their own. By the fourth quarter, the only question left was how high the home total would climb. Brock Purdy directed the show for San Francisco, throwing for a game-high 255 yards and a touchdown while spreading the ball to his playmakers. Christian McCaffrey was the centerpiece, piling up 136 receiving yards as a matchup problem no Denver defender could solve in space. The Broncos had a star of their own in Jonah Coleman, who churned out 178 rushing yards to keep Denver within striking distance. Coleman's production kept the visitors honest, but it never quite kept pace with the 53 points on the other side. Defensively, San Francisco made the plays that mattered most. Jack Jones came away with the game's lone interception, a takeaway that swung possession and field position at a moment when Denver badly needed points, and Upton Stout added the afternoon's only sack. Ja'Quan McMillian led all tacklers with six for the Broncos, a stat line that spoke to how often Denver's defense was on the field. Once the Niners cashed in off the turnover, the margin stretched beyond reach and the 22-point final was set.
