Mayweather, 43 and with an unblemished record of 50-0, last fought professionally in August 2017 when he won by TKO over mixed martial arts champion Conor McGregor, who was making his boxing debut.

The five-weight division world champion said he will step into the ring on Feb 20 at a yet to be determined venue to face Paul, who has a record of 0-1, with that loss coming against fellow YouTuber KSI.
