Mayweather Promotions Has Cancelled All Public Events Due To The 69 Vs Broner Beef. Potential security threats to boxers set to fight Saturday night at Barclays Center in Brooklyn have caused organizers of the card to alter the schedule of events leading up to it. A TMZ.com report Tuesday suggested that a social media beef between Adrien Broner and rapper Tekashi69 were at the root of the schedule changes. Tekashi69, according to TMZ, is believed to be well-connected to the Bloods, particularly in New York. The rapper, whose real name is Daniel Hernandez, is from Brooklyn.
