Floyd Mayweather Jnr’s obligation to fight former heavyweight champion Mike Tyson in a promised exhibition is leading to plans for an early fall doubleheader that would also include a Manny Pacquiao exhibition, officials connected to the arrangement told BoxingScene Monday. That would be followed by the Mayweather-Tyson showcase along with the Pacquiao exhibition against a yet-to-be-selected opponent either in late September or early October, with Miami and Dallas currently positioned as the frontrunners to land that event. “That would solve everything,” one official said of the financial disputes that currently exist between Mayweather and CSI Sports Events. One potential wrinkle in the doubleheader plan is that record eight-division champion Pacquiao, 62-8-3 (39 KOs), is seeking to negotiate a possible professional fight in the interim. 4 in the WBO rankings, Pacquiao would be eligible to fight unbeaten WBO welterweight champion Devin Haney if the sanctioning body approves the bout.
