Conor McGregor and Dustin Poirier clash in the early hours of Sunday morning as the Irishman returns to the octagon.
The bout takes place in Abu Dhabi at 9am local time and will be followed by a post-fight press conference, which you can watch live in the video at the top of this article.
McGregor has vowed to beat the American in less than 60 seconds.
On his prediction, he said: “I got him out of there in 90 seconds the first time, so I’m not that far off.
“That’s a complete confidence in my preparation and in my abilities. I know there’s questions about my abilities.
"I know he’s heavier and on a different weight and more experienced, but I feel I can do it. … I believe I can get him out there and possibly hit him early, but I am hoping for a good, long bout.”
But Poirier, who is second and two places ahead of McGregor in the lightweight rankings, is confident that he can cause an upset.
He commented: "My whole career has aligned me for tomorrow night. I'm here to be victorious and have my hand raised by any means necessary. I'm leaving it all out there, let's go."
