The Chicago Bears finished their preseason undefeated at 4-0 after defeating the Kansas City Chiefs 34-21, marking their first perfect preseason since 1994. Backup quarterback Tyson Bagent excelled, solidifying his role as QB2 with a strong performance, while running back Velus Jones Jr. also impressed with 111 rushing yards. Historically, teams with a preseason point differential of +60 or more have a track record of making the playoffs; the Bears achieved a +68 differential, the highest since 2013. The game was briefly interrupted due to an injury to cornerback Douglas Coleman III, who was immobilized and taken off the field. The Chiefs, resting their starters, noted the opportunity for depth players to showcase their skills ahead of the regular season. Additionally, the Chiefs extended center Creed Humphrey's contract, making it the largest for a center in NFL history.
