College football rivalry week was turned up a notch this year thanks to an outbreak of attempted flag plantings. It's not exactly a new trend, as former Oklahoma QB Baker Mayfield can attest to. He may have been one of the first that people remember doing the act when he did so at Ohio State in 2017.

Ohio State and Michigan, one of the sport’s most heated rivalries, started the day’s chaos when a fight broke out after the Wolverines upset the No. 2 Buckeyes. A group of Michigan players attempted to plant a UM flag at midfield at Ohio Stadium. The fight got so heated that multiple law enforcement agencies had to step in and break it up.

There were equally ugly scenes at the Kenan Memorial Stadium in Chapel Hill, as North Carolina (NC) State defeated the University of North Carolina (UNC) 35-30 for its fourth consecutive win in the rivalry game. Running back Hollywood Smothers punched in a two-yard touchdown to give NC the lead with 25 seconds left in the game.
