 At the sold-out American Airlines Center in Dallas, Diaz lost a unanimous decision in a 10-round, 185-pound boxing match against the YouTuber-turned-boxer.

Throughout the fight, a number of typical Diaz-style taunts were on display that put the mental focus of Paul to the test. The mind games did little to rattle Paul, who cruised his way to a win on the scorecards.

McGregor wasn’t pleased with what he saw from the two men, initially being critical of Diaz in a series of Tweets Sunday evening. McGregor then targeted Paul, who responded, prompting and ugly back-and-forth exchange.
