In August last year, Conor McGregor swapped the octagon for the boxing ring to take on the legendary American, who won in the 10th round to extend his perfect record to 50-0.
Having retired from boxing, Mayweather appears set to make McGregor's move in reverse and try his hand at mixed martial arts.
Last week, Mayweather confirmed he is to begin MMA training with UFC welterweight champion Tyron Woodley while he has previously teased a potential rematch with McGregor on social media.
"Not yet, everything takes time," Mayweather told TMZ when asked if he had applied for his licence.
"Eventually, we're going to apply for the licence. Hopefully, we can fight.
"It will probably be a little bit longer. Even if it takes six to eight months.
"Whatever it takes, we want to make sure that everything is done correctly and everything is done the right way."
