As Fox sportscasters covered the Michigan Wolverines’ stunning triumph over the Ohio State Buckeyes during Rivalry Week, a massive brawl broke out on the field, with players cut off mid-interview and expert analysis interrupted.

The 13-10 upset, played Nov. 30 at Ohio Stadium in Columbus, Ohio, marked the home team’s fourth straight loss to the arch-rival Wolverines, who entered the game as underdogs with a 6-5 record , compared to the Buckeyes’ 10-10 loss. 1. The loss effectively knocks the team out of the Big Ten Championship.

According to video footage and ESPN reports, mass fighting broke out after Michigan players and fans attempted to plant their flag at midfield at The Horseshoe. The Buckeyes and those in attendance rushed to stop them, and in the eventual five-minute standoff, players and coaches were bloodied and an Ohio State University police officer was injured. After the police used pepper spray, blows broke out and the fight was broken up.

According to a report from CBS Sports, flag-raising is not an unknown concept, although it was used in full force during college games during Rivalry Week, leading to a few altercations – though none on the magnitude of Michigan-Ohio State .

Footage of the moments before the fight shows Ohio State University defensive end Jack Sawyer ripping the Michigan flag away from a fan. The television broadcast showed players wiping their eyes and coughing after pepper spray was distributed. Eventually, law enforcement — who said they would continue to investigate the incident — lined up at midfield to separate the two teams.

“When you have such a great game, you hate to see something like that after the game. Bad for sport. “Bad for,” Michigan running back Kalel Mullings told Fox afterward. “At the end of the day, some people had to learn how to lose. You can’t fight this stuff just because you lost the game. All these fights, we had 60 minutes, we had four quarters for all these fights and now people want to talk and fight. That’s wrong. It’s bad for the game. Classless in my opinion. People need to do better.”
