In a strong showing at home, the Arizona Cardinals topped the San Francisco 49ers with a final score of 34-17, marking an impressive start to their 2027 season. With both teams looking to establish momentum early on, the Cardinals managed to seize control, showcasing their offensive firepower against a tough divisional rival. Quarterback Justin Fields led the charge for Arizona, throwing for 222 yards and two touchdowns, demonstrating his ability to command the offense effectively. Deuce Alexander was his top target, racking up 81 receiving yards, while Christian McCaffrey of the 49ers kept the game competitive with a solid 114 rushing yards. However, it was Fields' precision that ultimately made the difference in the Cardinals' victory. Defensively, the Cardinals stepped up when it mattered most, with Jailin Walker snagging an interception to halt a potential scoring drive from the 49ers. The turning point came in the second quarter when Arizona's defense forced a turnover that led to a quick touchdown, allowing them to build a lead that San Francisco could not overcome. Despite strong individual performances, the 49ers struggled to find their rhythm against a relentless Cardinals squad.
