49ers vs. Broncos: 3 defensive threats San Francisco must account for

The undefeated San Francisco 49ers face a dangerous Denver Broncos defense in Week 4, with 49ers Webzone highlighting three key defensive threats. Former 49ers safety Talanoa Hufanga returns to Levi's Stadium after posting two interceptions, a sack, and a defensive touchdown against the Los Angeles Rams. Defensive lineman Zach Allen and cornerback Patrick Surtain II are also named as pivotal disruptors who can alter San Francisco's game plan.

49ers quarterback Brock Purdy enters the game as the NFL's only qualified quarterback yet to be sacked this season. The article emphasizes that Allen's interior pressure poses a threat to Purdy's pocket, while Surtain's lockdown capability allows Denver defensive coordinator Vance Joseph to dedicate more defensive attention toward Christian McCaffrey and George Kittle.
