Is this college team the dirtiest in football?

A university side has been labelled the 'dirtiest team in football' after video emerged of some pretty questionable tactics during a game.

The UMass Beacons were taking on Haverford College when three players attacked their opponents in separate incidents during an NCAA Tournament.

One Beacons player, dressed in the dark uniforms, was red-carded after he picked up the ball and booted it into his opponent's face after being fouled.

Just minutes later, one of his teammates got away with a blatant headbutt.

Fellow Beacons player Ocane Williamson then lashed out at his defender while chasing down a loose ball.

He then grabbed another Haverford player in a headlock and threw him to the ground – also receiving a red card for his actions.

And to cap things off, he delivered another headbutt to the referee on his way off the field.

Despite being two men down the Beacons still managed to win on penalties.
