Last week, news broke that the best boxer on the planet Floyd "Money" Mayweather was going to come out of retirement and fight UFC star Conor McGregor. UFC president Dana White said that the fight wouldn't happen because McGregor is under contract to fight for the UFC.

In a recent interview, Mayweather said that the fight might just not be a rumor and can actually happen.

Over the weekend, McGregor posted a picture on his Instagram account that features a fight poster for the upcoming super fight.

So are these two fighters actually thinking of fighting each other, or is McGregor just using this to get back at the UFC for taking him off the UFC 200 card. One thing's for sure, if this fight is gonna happen, the UFC has to give it's blessing and it will take a lot for that to happen.
