The San Francisco 49ers suffered a crushing 28-18 defeat at the hands of the Kansas City Chiefs on Sunday at Levi’s Stadium. The loss not only marked the 49ers’ fourth of the season but extended head coach Kyle Shanahan’s winless record against Andy Reid’s Chiefs to 0-5. San Francisco now sits at 3-4, one game behind the NFC West-leading Seattle Seahawks.
The 49ers struggled throughout the game, particularly on offense. Quarterback Brock Purdy, who has shown flashes of brilliance this season, endured a miserable day under center. He completed 17 of 31 passes for 212 yards but threw three costly interceptions. Despite a couple of one-yard rushing touchdowns, his inability to manage the passing game hindered San Francisco’s efforts to mount a serious challenge.
Purdy’s struggles were exacerbated by injuries to key players. Wide receiver Brandon Aiyuk was carted off late in the second quarter after a low hit appeared to cause a significant knee injury. Early reports suggest that the 49ers fear Aiyuk may have torn his ACL, an injury that would end his season. This blow came on the heels of fellow wideout Deebo Samuel being ruled out due to illness. The 49ers, already without Jauan Jennings due to a hip injury, were forced to rely on rookies Ricky Pearsall, Jacob Cowing, and veterans Chris Conley and Ronnie Bell in their passing attack. The receiving corps struggled to create separation against Kansas City’s elite secondary.
While the 49ers’ offense faltered, their defense showed signs of life, despite being overwhelmed late in the game. Defensive lineman Nick Bosa recorded multiple pressures and a sack, while second-year linebacker Dee Winters laid a crushing hit on Chiefs running back Kareem Hunt in the first half. Rookie safety Malik Mustapha also impressed with 12 tackles, showcasing his potential as he started in place of injured safety Talanoa Hufanga.
One of the few bright spots for the 49ers’ defense came when defensive tackle Kalia Davis intercepted a pass from Chiefs quarterback Patrick Mahomes in the red zone, a critical play that kept the scoreline close for much of the first half.
Despite the 49ers’ defensive efforts, the Chiefs took control when it mattered most. Kansas City opened the game with a trick play, attempting a fake punt that San Francisco’s special teams unit successfully snuffed out. However, the 49ers failed to capitalize on the ensuing possession, setting the tone for a day full of missed opportunities.
Mahomes, though not at his best statistically, made pivotal plays when necessary, including a 33-yard scramble that set up a touchdown early in the fourth quarter. His 1-yard QB draw touchdown extended the Chiefs’ lead to 21-12, a deficit the 49ers could not overcome.
The Chiefs’ defense, led by defensive coordinator Steve Spagnuolo, put constant pressure on Purdy. Kansas City defensive end George Karlaftis and safety Jaden Hicks both came up with interceptions, with Hicks sealing the game by picking off Purdy in the end zone during the 49ers’ final desperate drive.
The 49ers’ injury woes were a major storyline coming into the game and only got worse as the day progressed. Aiyuk’s potential season-ending knee injury is a devastating blow for a team already depleted at the wide receiver position. With Samuel and Jennings both sidelined, the 49ers will likely need rookie Ricky Pearsall to take on a larger role in the coming weeks.
San Francisco will need to regroup quickly if they hope to salvage their season. With a 3-4 record, the 49ers are now looking up at the Seahawks in the NFC West standings. They face another tough test next week as they take on the Dallas Cowboys in a critical Week 8 matchup.
