Conor McGregor appears to have an opponent in mind for his return to the Octagon.
The former UFC lightweight and featherweight champion replied to a tweet from the promotion Wednesday, wishing veteran Frankie Edgar a happy birthday and hinting at a December fight between the two.
Edgar, a former UFC lightweight champion himself, responded to the message, claiming he's already agreed to battle McGregor.
McGregor seemed open to the bout, encouraging UFC president Dana White to finalize it.
McGregor, 31, hasn't fought since current lightweight champion Khabib Nurmagomedov submitted him at UFC 229 in October 2018.
The Irishman has run into a number of legal issues since that bout and announced his retirement from MMA in March, though White viewed it as a ploy to secure an ownership stake in the UFC.
