We spoke about this above and it is something that has to be explained a bit further. Floyd Mayweather reported that he was going to send money to Logan Paul that Paul deserved from the fight, and Paul said that he has not received this money. Paul has also mentioned that he was going to take Floyd Mayweather to court, but that has not yet happened.
The world is uncertain about how much they do owe one another, but Logan Paul has made it seem like it is a few million dollars. If Mayweather does not pay this in the next few months, there is a possibility that Logan Paul will actually take him to court.
