There won’t be as many students in attendance for Virginia Tech’s football game this weekend due to “embarrassing” behavior.

The university said in a statement that student attendance will be limited starting this Saturday against Pitt due to “selfish, inappropriate, and embarrassing student behavior” at previous games. Student attendance will be restricted to season ticket holders and a limited number of lottery winners, along with new guidance for gate entry and an increased security presence.

While the school didn’t specifically say what kind of behavior prompted the move, there had been growing concern about the stadium experience among students.
