But, even though it was a smash hit -- there's a ton of work and cost associated with the F.I. cards -- and fans wondered if the UFC would ever go back.
Not only are they returning ... Dana says Fight Island will soon be the number 1 destination for combat sporting events across the world.
"I'm telling you right now, Abu Dhabi is gonna become the fight capital of the world! Place is gonna end up being the fight capital of the world. The stuff that we're doing over there, the infrastructure that's already been built, the stuff that we're talking about doing, this place is gonna be a destination."
"If you are a fight fan, everybody wants to come to Fight Island man. You know? Because it's f**king cool! It's fun and it's a really unique experience right now with all this weirdness that's going on in the world."
