Mayweather-Mckernan fight is set for May 2 on Barclays Center in Brooklyn, according to a source.
The fight will be broadcast on HBO Pay-Per-View and ESPN.
Mayweather-Dowling bout will be on HBO PPV.
Mayweather’s next bout is scheduled for June 1 on HBO, and he has an opponent in the middleweight division.
The two-time world champion will face Bermane Stiverne on May 9 in Las Vegas, but the HBO PPVs date is yet to be confirmed.
Mayweather is still awaiting word from the Nevada State Athletic Commission about whether he will be able to return to the ring against Stivernes opponent.
The commission has been conducting a review into Mayweather’s fight with Manny Pacquiao, but has not issued any ruling.
Mayweather has not been tested in a year, and it is unclear if he will still be able for the May 2 fight.
