San Francisco 49ers defeat Denver Broncos to remain undefeated

The San Francisco 49ers maintained their undefeated record through four games following a Week 4 victory over the Denver Broncos. During the postgame confrontation, 49ers linebacker Dre Greenlaw attempted to confront Broncos coach Sean Payton, telling him to “get the f— off my field.” Greenlaw later confirmed the exchange to reporters. Teammate Fred Warner intervened to prevent further escalation. Despite the tension, Payton expressed respect for Greenlaw, noting their previous time together in Denver.

Key performances in the victory included the 49ers' offensive line, which prevented Brock Purdy from being sacked for the fourth consecutive game. Additionally, Mike Evans led the team in catches and yards despite appearing to play with fractured ribs, and George Kittle continued his high-level play following a previous Achilles injury.
