Floyd Mayweather rips Conor McGregor on Instagram

Floyd Mayweather Jr. continues to take swipes at UFC lightweight champion Conor McGregor, this time posting a video of the latter tapping out to Nate Diaz on Instagram. The retired pound-for-pound boxing king even offered $10,000 to the person who best captions the video. Mayweather would later go on Instagram Live to call McGregor "Conor McTapout" and conduct a fake interview with a man mocking McGregor's Irish heritage. Despite months of buildup and rumors, along with McGregor obtaining a boxing license in California recently, there appears to be no indication of a possible showdown in the boxing ring between the two.
