Conor McGregor and Donald Cerrone will come face to face tonight at the official press conference ahead of their clash at UFC 246.
The rivals have not had the chance to exchange insults since their fight was officially announced last year.
But they will do so next week with the public welcome to attend the event which will be held in the Pearls Theatre in the Palms Casino in Las Vegas.
The press conference is due to start at 5pm local time (1am UK time) with doors opening at 3.30pm.
McGregor is fighting for the first time since he was choked out by lightweight champion Khabib Nurmagomedov 15 months ago.
He will take on Cerrone at welterweight and insists this will be the first of three fights in 2020 as he plots another tilt at a title.
"Me and Donald have had a history and I have said I'd fight him," McGregor told The Mac Life.
"If you look at the list of people I've called out and engaged with, Donald was probably one of the first ones. He's first on the list, I'll get to every single one of them also.
"I'll have a good solid camp at 170 with no weight cut, a good fight; I know Donald is a good fighter, he has great records, the most knockdowns, the most head kicks, the most fights, most rounds... he has a lot of UFC records under his belt.
"I'll get a great camp, a great fight and it will take me into the year. I'm looking at this as a season so it's the beginning of the season.
"Donald was the first fight I agreed to have a fight with."
