Rivalry week matchups are always heated with tensions and resentments building. But four annual clashes ended with fights between opponents when the winning road team attempted to plant a flag on the home field of their adversary to punctuate its victory.

Controversy erupted after the game when the trophy was nowhere to be found. According to the 24/7 Sports account "Fight Massachusetts," both programs were reportedly opposed to the introduction of the new trophy.

College football was dominated by flags on Saturday. Not the ones thrown by officials — the ones planted by players in the middle of the field. Michigan, North Carolina State and Florida celebrated road wins by displaying flags on the logos in the middle of their rivals' stadiums.
