In a thrilling Week 18 matchup, the San Francisco 49ers topped the Arizona Cardinals 35-26, solidifying their playoff positioning as the regular season comes to a close. Both teams came into the game with something to prove, but it was the 49ers who emerged victorious, showcasing their offensive prowess. Brock Purdy led the charge for San Francisco, throwing for three touchdowns and delivering a standout performance. Christian McCaffrey contributed significantly on the ground, racking up 98 rushing yards, while Deebo Samuel and Brandon Aiyuk combined for key receptions that kept the chains moving. On the other side, Carson Beck put up impressive numbers with 263 passing yards, but it wasn't enough to keep pace with the 49ers’ offense. Defensively, the 49ers made crucial plays that shifted momentum in their favor. Mykel Williams recorded a sack that stifled a Cardinals drive, while Ji'Ayir Brown's interception proved to be a game-changing moment, halting Arizona's momentum just when they were looking to rally. Zaven Collins led the Cardinals in tackles, but it was San Francisco's ability to create turnovers and pressure the quarterback that ultimately determined the outcome of this hard-fought contest.
