The latest Broncos vs. 49ers weather report calls for a heat advisory covering Santa Clara as Denver visits unbeaten San Francisco today at 4:25 p.m. ET (CBS) from Levi's Stadium.
The forecast ahead of kickoff calls for temperatures climbing into the low 90s during the game. That could make it tough to keep players fresh during today's matchup, particularly for a San Francisco defensive line already missing several pieces.

How weather could impact Broncos vs 49ers
San Francisco remains without defensive linemen Nick Bosa, Mykel Williams, and James Thompson Jr. The 49ers added depth Saturday by promoting Sebastian Valdez and elevating Matthew Judon, but sustained drives in the heat could still test that rotation. Jaylen Waddle is cleared to play alongside Courtland Sutton, giving Bo Nix two established targets to help keep those drives moving.
J.K. Dobbins is also cleared to play, meaning Denver will its leading rusher in tow against that depleted front. The Broncos are averaging just 81 rushing yards per game, though, so Dobbins still needs a strong performance to help Denver to establish its ground game. Productive early carries would help Denver extend drives and give its own defense a break from chasing an explosive offense behind Brock Purdy's MVP-level start.
Christian McCaffrey's role as both a runner and receiver gives him plenty to do in the heat, but the forecast alone isn't a reason to bench him in fantasy. Mike Evans will play despite his rib injury, but the heat could force San Francisco to rotate through its various passing options today in order to stay fresh.
