One of the videos showed several Spartans, including Itayvion Brown, Zion Young and Angelo Grose, attacking Michigan defensive back Jaden McBurrows.

Head coaches of both teams, Michigan State's Mel Tucker and Michigan's Jim Harbaugh were seen trying to direct their players to the respective locker rooms.
