Early Sunday morning Floyd Mayweather posted a photoshopped picture on social media of himself and Conor McGregor inside the Octagon with the caption, “Certified Killa vs Certified Bitch.”

The picture continues to fuel rumors of an MMA fight between the two.  It also prompted McGregor to respond and he did so with a real picture of himself in the Octagon captioned, “A real elbow in a real fight.”

The promotion of their next big fight has already started.  Don’t be surprised if an MMA fight between Mayweather and McGregor takes place.  There’s just too much money to be made.
