Conor McGregor Finds His Biggest Competition Yet & It's Not Who You'd Expect: "Forget Floyd, Forget Nate, Forget Khabib & Forget Tony" –

UFC superstar Conor McGregor has some real beef on his hands these days – literally. The MMA fighter has trolled his competition from Floyd Mayweather Jr. to Nate Diaz in a new Burger King campaign.

McGregor went to Instagram Monday (March 5) to hilariously flex his new partnership with the fast food franchise.

Recently, Conor went to his Instagram page and appeared to suggest Floyd would never fight in the UFC.

Last month, Mayweather tossed up a fake pic himself banging up McGregor MMA-style.
