sections. I worked on Event Staff when I was at BYU, and that was always specifically mentioned in our training meetings. Opposing fans are free to sit in general seating, but the Student Section at any BYU game, match, etc. is for BYU fans only. If they're willing to cover up the opposing team's gear and refrain from cheering against BYU they are allowed to stay in the student section, otherwise they must go find a seat elsewhere.
