Conor McGregor must love the attention because just days after Dana White & the UFC squashed rumors of him and Floyd Mayweather fighting he starts them right back up by posting this on Instagram.
McGregor is a smart business and fighter, so there must be a reason for this Mayweater tease.
Will the two ever fight? Probably not, but McGregor could be using this to further show the UFC that he has the UFC that he has earning potential outside of their promotion.
