In a thrilling Week 3 matchup, the San Francisco 49ers outlasted the Arizona Cardinals with a final score of 51-40. The stakes were high as both teams aimed to establish early-season momentum in a competitive division, but it was the 49ers who emerged victorious in a high-scoring affair. Brock Purdy shined for San Francisco, throwing for three touchdowns and racking up an impressive 174 rushing yards, showcasing his dual-threat capability. Christian McCaffrey contributed significantly as well, leading the receiving corps with 121 yards, proving to be a reliable target throughout the game. Carson Beck of the Cardinals also had a solid performance, finishing with 232 passing yards but ultimately fell short against the 49ers' explosive offense. Defensively, the Cardinals struggled to contain Purdy's dynamic play, and the turning point came in the second quarter when San Francisco scored two quick touchdowns to take a commanding lead. Mack Wilson Sr. led Arizona's defensive efforts with four tackles and a sack, but it was not enough to slow down the 49ers’ relentless attack. Cody Simon did manage to snag an interception, but the Cardinals' defense could not capitalize on key opportunities, allowing San Francisco to maintain control throughout the contest.
