49ers vs. Broncos: 3 keys to victory in Week 4

The undefeated San Francisco 49ers host the Denver Broncos in Week 4 after surviving a narrow 36-30 victory over Arizona. Denver enters the matchup at 2-1 following a 30-26 comeback win against the Los Angeles Rams. 49ers Webzone highlights three primary keys for San Francisco: disrupting quarterback Bo Nix, maintaining Brock Purdy's zero-sack streak, and closing out leads decisively to prevent another Denver comeback.

Denver quarterback Bo Nix has thrown an interception in each game this season, presenting opportunities for San Francisco's defense to force rushed decisions. Meanwhile, the 49ers offensive line has not allowed a sack on Brock Purdy through three games, which the article notes will be crucial against a opportunistic Broncos defense featuring former 49er Talanoa Hufanga.
