The Fresno State football coach addressed the violence that took place in the stands during the Bulldogs' 40-14 loss Saturday to Boise State.
The crowd at the game was the first sellout crowd at Bulldog Stadium since 2014, according to KFSN-TV.
Fresno State coach Kalen DeBoer called the incident unfortunate and said the program will make efforts to prevent it from happening again.
"This program is run from top to bottom with class, and the people that support it and come to our games are the same way,” DeBoer said.
The brawl lasted several minutes and spilled out of the stands and into the concrete concourse below, KFSN-TV reported.
Videos of the incident on social media have gone viral. Videos posted to social media showed punches being thrown in the north endzone bleachers.
"We just got to be smarter and understand that's not going to be accepted here, that's not what we stand for," DeBoer said.
Fresno State Police told KFSN-TV that multiple people related to the fight were arrested Saturday night.
"Ninety-nine percent of who was in the stadium, more than that probably, came here for sheer entertainment," DeBoer said during his weekly news conference Monday. "We really don't want you here if that's what you're coming for."
KFSN-TV reported that alcohol was banned from Bulldog Stadium in 2006, but allowed back in 2017.
