49ers seek to maintain unbeaten record against Broncos on Sunday

The San Francisco 49ers host the Denver Broncos on Sunday, aiming for a 4-0 start after wins against the Dolphins and Cardinals. The 49ers, 3-0, have faced criticism regarding the quality of their opponents, which included a struggling Rams team. The Broncos, 2-1 and coming off back-to-back victories against playoff teams, aim to challenge the 49ers' offense led by quarterback Brock Purdy, who has thrown nine touchdowns in three games. Denver's defense will need to improve from its current ranking at 29th in yards allowed per game to compete effectively. Both teams are looking to solidify their positions in an early season matchup with implications for playoff contention.
