Will he or won't he?

It might not even be something that needs to be answered after UFC 205. Conor McGregor will have to beat Eddie Alvarez — no easy task — on Saturday night in New York to win the lightweight title for this issue to even come into effect.

But it could. McGregor, the UFC featherweight champ, could end up being the first UFC fighter to hold two different titles in different weight classes at the same time. And, if he does, there's no doubt the UFC will ask him to drop one of those belts. Many fans will have the same reaction.

Whether or not "The Notorious" gives one up? That's still up for debate. McGregor has implied in the press that he would. But he has also vehemently said he would not.

John Kavanagh, his longtime coach, told Ariel Helwani on Monday's edition of The MMA Hour that he has heard no murmurs from McGregor about losing a belt if two end up in his possession.

"I have not heard a hint of him giving up the belt," McGregor said. "He has never said to me, ‘Oh, I'm gonna hand back the 45 or the 55.' Any time I've heard him talk about it, he's been very clear, very loud, very vocal about saying he fights very often. Look how close he is from fighting, literally just a couple of months ago. It's not unusual for a champion to defend the belt once a year or twice a year."

It's true. McGregor will have fought four times in 11 months dating back to last December's 13-second knockout of Jose Aldo. He's perhaps the most active star in UFC history, especially considering how much money he draws every time out.

"So, why not?" Kavanagh said.

Well, there are already some people in an uproar that McGregor has yet to defend the featherweight title. He fought Nate Diaz twice this year, foregoing clear potential title defenses against the likes of Frankie Edgar and Aldo. There are also lightweight contenders lining up for the winner of Alvarez-McGregor. Tony Ferguson and Khabib Nurmagomedov have both done more than enough to earn a chance at the strap.

Going back and forth and defending both belts would be nary impossible. But Kavanagh said McGregor could try it. Before, the coach was worried 145 might be too low for McGregor to go now. He's just very big for that weight class. But Kavanagh has changed his tune because of the presence of noted nutritionist George Lockhart.

"[Featherweight] for him now I believe would be easier than what 45 for him was when we did it for let's say his first two or three fights in the UFC," Kavanagh said.

Back then, Kavanagh said he was Googling ways to get off the weight. Now, Lockhart has been living with McGregor in Ireland, making every meal for him. Kavanagh said McGregor is lighter as of Monday than he was on the Monday of fight weeks in which he competed at 145.

"Now because of the type of people we have involved, I don't see the physical problem with it," Kavanagh said. "I won't lie and say it's not easier for 55.

"If a 45 fight came along and he was like, ‘I have to do this,' I'd be behind it."

Would the UFC and others be, though? That remains to be seen.
