The Arizona Cardinals triumphed over the San Francisco 49ers with a final score of 38-21, securing a crucial victory in Week 18 of the 2026 season. This win not only showcased the Cardinals' dominance but also solidified their playoff positioning, while the 49ers are left to ponder their next steps after a disappointing end to the regular season. Brock Purdy of the 49ers had a solid outing, throwing for 236 yards and two touchdowns, demonstrating his ability to lead the offense effectively. However, it was Jeremiyah Love who shone for Arizona, rushing for 88 yards, and contributing significantly to the ground game. Mike Evans also stood out for San Francisco, racking up 110 receiving yards, but it wasn't enough to propel his team to victory. Defensively, Jarrick Bernard-Converse was a game-changer for the Cardinals, recording four total tackles and two crucial interceptions that stifled any momentum the 49ers tried to build. The turning point came in the second half when Bernard-Converse's second interception led to a quick touchdown, allowing Arizona to pull away and ultimately secure the win. Gracen Halton's 1.5 sacks for the 49ers kept the pressure on, but it wasn't enough to overcome the Cardinals' balanced attack and defensive prowess.
