Thousands of Iowa fans ran onto the field on Saturday, tearing down a goal post after the Hawkeyes' 45-21 victory at Minnesota.
Three people were arrested on charges of damaging property.
The fans jumped the lower deck railing and massed near Iowa's bench to celebrate its unbeaten Big Ten season. It appeared the fans started to calm down when the public address announcer loudly urged them off the field, stating it was their "final warning."
A high-pitched squeal started emanating from the loudspeakers, prompting some to head to the stands. But the majority swarmed the south end zone, and after a few tries, tipped over the post.
The crowd moved toward the north end, but the goal post was surrounded by a six uniformed officers and security guards.
