The much-desired Conor McGregor vs Floyd Mayweather is a start-stop development. Will they, or won't they? The two seem to have plenty to say about each other on social media, and Money Mayweather gets the latest jab in with his Instagram post. After stating that McGregor's California boxing license is just a mere smokescreen, the undefeated boxer posted a photo of a bloodied McGregor lying in the middle of the octagon after his loss to Nate Diaz, and Floyd is offering an unreal TEN THOUSAND DOLLARS for the best caption.
