Rivalry Week in college football stirs up some crazy stuff as emotions run hot. That certainly was the case in Tucson as Arizona prepared to host Arizona State Saturday.

The two teams got into a skirmish a couple of hours before the game.



Afterward, a police presence was required on the field to keep the two teams separated during warm-ups.

And according to an eyewitness, per Chris Karpman of 247 Sports, the players weren’t the only ones getting involved in the skirmish, either.



Hopefully cooler heads will prevail once the actual games kicks off later this afternoon.
