And when he does, there won't be a shortage of 155 standouts ready and willing to welcome him to "one of the hardest weight classes" in the game. Among them is former division kingpin, Anthony Pettis, who declared during the UFC on FOX 16 post-fight show that he's down to tango with the Irishman.
"What's next for me is getting my belt back. This guy that beat me last has my belt and I want that back. That's the big thing on my mind right now. But, Conor McGregor, I heard he's moving up to 155, so I'll welcome to one of the hardest weight classes for sure."
As for Conor, he has some unfinished business to take care of against Jose Aldo, as the men are expected to settle their differences sometime this year and unify the titles after McGregor defeated Chad Mendes to claim the interim strap (see it).
Should Pettis and McGregor ever ind themselves locked inside the cage, who are you picking to prevail?
