In a tightly contested match at Levi's Stadium, the San Francisco 49ers faced another disappointing defeat at the hands of the Arizona Cardinals, losing 24-23. This game not only marked a significant collapse for the 49ers, particularly in the second half, but also raised questions about quarterback Brock Purdy's performance after he threw an interception during a critical moment. Head coach Kyle Shanahan expressed his frustration over the team's inability to maintain a lead, while Nick Bosa identified the collapse as a team issue. Despite the loss, some players like Bosa viewed playing despite the grueling conditions as a 'blessing in disguise.' The defeat drops the 49ers to 2-3 for the season, with fans braving the heatwave to support the team, further complicating an already challenging season.
