Mayweather hasn't fought since and has been spending his time travelling the world.
Nurmagomedov is now suspended by the Nevada Athletic Commission (NSAC) for his actions following his fight with Conor McGregor at UFC 229.
The two shared 12 rounds in the ring back in 2016, with Mayweather winning by majority decision.
"Oh, we fighting. He called me out".

"I'm my own boss, so I can't say what's going on on Khabib's end".
Oh, and he did say that he and Khabib are going to fight, which we hope he's wrong about. "It's very important. We have something pending there, so let's make the second fight". Mayweather on Wednesday told TMZ he's willing to fight Khabib Nurmagomedov for a "nine-figure payday", but New Year's Eve nearly certainly is too soon for them to square off. It has also been reported that Mayweather would come out of retirement and fight in the UFC in a rematch with McGregor. Probably $100m more, guaranteed.
Mayweather's company CEO, Leonard Ellerbe, recently ran into Khabib in Russian Federation during the World Boxing Super Series and shared a video of the 27-0 UFC star asking Mayweather for a fight.
McGregor had been eyeing a rematch with Mayweather following his 10th-round TKO loss previous year. "If he wants to return, I ask him to look my way to give a great fight to the fans". Because in the jungle, there's only one king.
The undefeated UFC lightweight champion had previously pushed for the bout to take place in any location other than Las Vegas because of his ongoing issues with the Nevada State Athletic Commission.

"I saw on the interview, when he hit Conor McGregor, he hit Conor McGregor down. I'm gonna say somewhere between $110-$200 million guaranteed".
But UFC heavyweight champion Daniel Cormier, who is a teammate of Nurmagomedov, declared the match-up a joke. Khabib, you got my leftovers.
Floyd Mayweather Jr.is determined to end 2018 with a bang, if Manny Pacquiao is to be believed.
In a direct response to the fact that the Russian cited his second-round knockdown of Conor as a one-up of sorts over him, Mayweather was quick to make it clear that it mattered little.More news: Sears, the once-mighty United States retailer, files for bankruptcy
