At an event in Russia this past weekend, Nurmagomedov called out boxing legend Floyd Mayweather, speaking on camera next to Mayweather Promotions CEO Leonard Ellerbe.
Mayweather took to social media on Monday morning to respond. He posted on Instagram: "CBS, Showtime and MGM Grand get the checkbook out!"
A fight against Nurmagomedov would be Mayweather's second against a UFC fighter.
I'm pretty sure Conor McGregor can't be too happy about this.
What about his payday?
