Turki Alalshikh, the chairman of the General Entertainment Authority of Saudi Arabia and the most powerful man in boxing, had a little April Fools' day fun, tweeting out this message: "Dear fans, Today marks our final day in boxing. I want to thank everyone who has been part of this journey with me. To my dear friends scheduled to fight on the London and NYC cards, I apologize for the time and effort you put into training camp. I wish you the best of luck in your future fights, as those two events have now been officially cancelled. Yours, Turki"
