However, Mayweather Snr, who was present throughout the bad-tempered press conference, denied that McGregor's comments were racially charged. "This (guy) made $3 million his last fight, but we know that's training camp money for me". Yours truly (Marcin Migdal) will join Bradie at the conference.
Most fight fans realize the promotion for this bout could be more entertaining than the historic 154-pound fight August 26 in Las Vegas.
