Briana JeannelThe San Francisco 49ers held on in a nail-biting 16-15 win over the Arizona Cardinals in their home opener at Levi's Stadium. The victory marks the 49ers first 3-0 start since 2023, fueled by clutch defense, RBChristian McCaffrey's versatility, and a game-winning kick from newcomerEddy Pieiro. Bosa stripped Arizona's RB James Conner on Arizona's second drive, and although the Cardinals recovered, the forced fumble highlighted San Francisco's physicality. Resilient Finish After Late MistakesThe 49ers looked in control after Juszczyk's touchdown made it 13-6, but a few mistakes gave Arizona hope. The 49ers improve to 3-0 and will play back in Levi's Stadium, hosting the Jacksonville Jaguars on September 27 in Week 4.
