Conor McGregor is set to make his highly-anticipated return to the octagon when he faces Michael Chandler in the main event of UFC 303 in just under four weeks, ending a three-year hiatus from mixed martial arts. The fighters had been set to hold a promotional press conference in Dublin, Ireland on Monday, however, it was called off at the last minute, with no official reason provided for the cancellation.
Speaking on his ESPN show, Good Guy / Bad Guy, UFC Hall of Famer Daniel Cormier blamed 'The Notorious' for the cancellation, stating:
"The reason this is off is because Conor McGregor called it off. Michael Chandler would drag himself there with no legs to get to that presser. Michael Chandler would fight Conor McGregor on one leg to fight Conor McGregor."

The decision to not provide a reason for the cancellation has led to plenty of speculation, with a majority of the blame falling on McGregor. While there has been speculation that the fight itself could be canceled, there is nothing that has suggested that, at this point.
