At least two shots were fired during the altercation, with one bullet striking a school security staff in the back of the head.

The stadium was placed onto lockdown, Curley said. The unidentified security guard was taken to a local hospital and is in critical, but stable condition.

"We would also be remiss if we did not mention the heroics of this security officer and the others who attempted to break up the fight and put themselves in harm’s way so the spectators and students watching the game were not in danger," police said in the press release.

The police department first notified residents of the shooting in a social media post, saying that "all students at the game are safe and accounted for."
