Floyd Mayweather Jr. maybe actually taking his talents to the UFC if the money is right.

On Tuesday, Mayweather posted a short clip on Instagram of him stepping into an MMA cage, before Conor McGregor hilariously responded with “Keep up the good work, my son. Yours sincerely, Senior.”

The 14-second video is the latest in a series of recent social media posts from Mayweather.

On Monday, he posted a photo of him landing a punch on McGregor from their boxing match in August. And on Tuesday, Mayweather put up a short video of him stepping into an MMA cage.

Mayweather, of course, welcomed Conor McGregor to the boxing ring last summer, schooling the UFC lightweight champion before winning by 10th-round TKO in “The Money Fight” that did huge numbers and raked in a ton of cash. Mayweather said afterward that he was officially retired, but he continues to tease another possible crossover.

The idea of a 40-year-old with no MMA experience would have a chance in the octagon with an MMA champ is crazy. What is even crazier is the amount of money this potential fight would generate.
