In a high-octane battle in Week 3 of the 2026 season, the San Francisco 49ers triumphed over the Arizona Cardinals with a final score of 45-24. Both teams were looking to solidify their positions early in the season, but it was the 49ers who showcased their offensive firepower and controlled the game. Brock Purdy led the charge for San Francisco, tossing three touchdown passes while Christian McCaffrey dominated on the ground, racking up 164 rushing yards. For Arizona, Carson Beck threw for 273 yards, connecting with Marvin Harrison Jr., who had a standout performance with 190 receiving yards. However, the Cardinals struggled to keep pace with the explosive 49ers offense. Defensively, Fred Warner was a force for San Francisco, not only recording a sack but also intercepting two passes, which proved crucial in shifting momentum toward the 49ers. The turning point came in the second quarter when Warner's first interception led to a quick touchdown, allowing San Francisco to pull ahead and maintain control throughout the game. The 49ers' defense, combined with their offensive prowess, ultimately paved the way for a decisive victory.
