Video: Watch Conor McGregor's first round knockout over Dana White in EA Sports UFC

Conor McGregor holds back for no man, including Ultimate Fighting Championship (UFC) President Dana White. While in Toronto yesterday (March 27, 2015) for the UFC 189 World Tour, the UFC boss and "The Notorious" one stopped by TSN Studios and got in a quick EA Sports UFC match. McGregor played as himself of course, while Dana -- being the devil's advocate he is -- chose Jose Aldo to oppose the Irishman. In the end, one beating wasn't enough for the UFC boss, as McGregor virtually knocked out White twice -- both in the first round.
