CONAN O'BRIEN Challenges Conor To Fight

9:40 AM PT

- CoCo's in inconvenience ... 'cause Conor's taken notice, saying he's totally down for a fight ... and even tossed Imprint Wahlberg into the mix also!!!

"Challenge accepted Conan!" Conor tweeted. "I'll whoop you and Walhberg (sic) in the same night."

"Double shares for the Double Champ!"If Conor McGregor REALLY needs a piece of the UFC, he's going to need to get past Conan O'Brien first!!

CoCo was leaving UCLA on Wednesday subsequent to participating in a college signing day occasion with Michelle Obama when we raised the reality he happens to be a minority proprietor of the UFC.


And, with Conor making such a great amount of noise about wanting an ownership stake in the organization, we inquired as to whether he would follow Imprint Wahlberg's lead and offer to sell Conor a piece of his share.

"I will fight him for his [share]," Conan kidded ... "If he can take me in the Octagon!"

O'Brien continued to prod ... saying he'd need to take a gander at the administrative work before making any serious arrangement with Conor.

See, he's obviously joking the entire path through - yet Conor wasn't kidding when he demanded ownership.

Indeed, Conor still isn't signed on to take another fight in the Octagon in the wake of retiring via social media earlier this year.

The UFC

tried to book Conor to fight Cattle rustler Cerrone, yet that fell separated. McGregor says he needs a rematch with Nate Diaz ... in any case, that doesn't appear to come together soon either.
