UFC Champion Conor McGregor brought in former Boxing world champion Paulie Malignaggi for his training camp for Floyd Mayweather and beat the daylights out of him for 12 rounds.
UFC President Dana White released some of the footage online and caused quite a stir.
Conor was not supposed to be able to hang with a world champion boxer in the ring, instead, he made easy work of him.
Conor was finished by Floyd in the 10th round and had to be saved by the referee from permanent brain damage after not responding to a vicious assault from the hands of Mayweather.
Malignaggi joined Colin Cowherd on Fox Sports to talk about the fight.
