The Big Ten will not take disciplinary action against any players involved in the fight following Michigan's 24-17 win over Michigan State on Saturday.
The conference said in a statement that it was "inconclusive as to whether individual discipline was appropriate" after reviewing footage of the scene.
The fight occurred after Michigan kneeled down to seal the victory. Michigan's Colston Loveland and Michigan State's Anthony Jones appeared to grapple with one another before both teams rushed onto the field.
The Big Ten called the incident "a disappointing conclusion to the contest" and thanked staff, referees and security for breaking up the fight.
