A day after UFC lightweight champion Khabib Nurmagomedov issued a challenge to put his 27-0 MMA record on the line against Floyd Mayweather’s 50-0 boxing record, Mayweather took to Twitter to offer a response.
"CBS, Showtime and MGM Grand get the checkbook out!" Mayweather wrote.
Nurmagomedov was seen at a boxing event with Mayweather promotions CEO Leonard Ellerbe on the weekend and a clip was released in which Nurmagomedov proposed a fight between "two guys never lose," MMA Fighting Newswire reported.
A challenge from a UFC star is nothing new for Mayweather, who memorably feuded with Conor McGregor for over a year before the two engaged in the most highly publicized crossover fight in history. Mayweather went on to defeat “The Notorious” in a boxing match on Aug. 26, 2017, via 10th-round TKO.
