Kansas City Chiefs running back Isiah Pacheco suffered a fractured fibula during the team's 26-25 victory over the Cincinnati Bengals, leaving the game on crutches and in a walking boot. Initial tests confirmed the fracture, and further examinations will determine if there is additional ligament damage; he is expected to miss significant time, potentially landing on injured reserve. Coach Andy Reid acknowledged the seriousness of the injury, noting that Pacheco was undergoing tests but did not have an immediate timeline for his return. In the game, Pacheco had 90 rushing yards on 19 carries and contributed 21 receiving yards. The Chiefs are already managing without running back Clyde Edwards-Helaire, who is dealing with PTSD. Backup options include veteran Samaje Perine and rookie Carson Steele as the team adjusts to these injuries.
