The San Francisco 49ers faced a tough defeat against the Kansas City Chiefs, losing 28-18, but the game took a dramatic turn when Trent Williams was ejected for throwing a punch.

Late in the fourth quarter, after a confrontation with Chiefs defender Bryan Cook, Williams retaliated, leading to his ejection despite the lack of penalties for Cook. The incident highlighted the escalating tensions on the field, as the game had already been marked by physical play.
