It seems like the only fight for Mayweather that would make sense is a rematch with McGregor, considering the 15-time world champion could likely make at least another $100 million if he agreed to it. However, McGregor is still under contract with the UFC and is expected to get back to mixed martial arts fights. Showtime Sports executive vice president Stephen Espinoza told TMZ that he doubts a Mayweather-McGregor rematch would happen.There have been rumors about McGregor getting into the ring with another legendary boxer, but it would not be a surprise if the Irishman’s days of boxing are over. The same is likely true of Mayweather’s.
