Kansas State
Oklahoma State hosted Kansas State on October 3, 2015. Late in the second quarter, an officiating error gave Oklahoma State a first down when the offense was four yards short after the third down play. The series ended with a touchdown for Oklahoma State. The error brought into question Big 12 Conference officiating, especially in light that the game was on the 25th anniversary of the Fifth Down Game between the Colorado Buffaloes and Missouri Tigers. SB Nation published "K-State lost to Oklahoma State, 36–34. Inept Big 12 officials gifted Oklahoma State a touchdown.."
