It all started with the official UFC Twitter account asking the innocuous question, "Whose birthday is it?" alongside a photograph of Edgar.

McGregor replied, saying: "Happy birthday Frankie, see you in December," A clear nod to a potential showdown later this year.

Edgar said: "Thanks pal, I said yes already. It's on you and Dana White to make it happen."

With a lightweight fight seemingly in the works, McGregor said: "There you go, White, make the bout."

He even said the UFC could donate his earnings from the event to a first responder charity, the same one he gives to through his whiskey brand, Proper no. Twelve.

If the McGregor vs. Edgar fight were to go ahead, it would likely be added to the UFC 245 event at the T-Mobile Arena in Las Vegas on Saturday, December 14.

UFC 245 is currently is headlined by Kamaru Usman's welterweight title defense against Colby Covington.

It would be Conor McGregor's first fight for 14 months

McGregor has not fought since his conclusive, fourth round submission loss to the reigning UFC lightweight champion Khabib Nurmagomedov at UFC 229 last year.

He has since courted controversy for slapping a fan's phone out of his hand and walking away and for appearing to throw a punch at an older man in a Dublin pub. His entourage has also been accused of forcing a nightclub bottle service girl into their car after a booze-fueled evening in LA.

Rumors of a comeback have risen in recent weeks with Justin Gaethje, Dustin Poirier, and Edgar all linked with the Irish striker.

McGregor's coach John Kavanagh recently told Business Insider, "bring them all on."
