UFC fans have been warned that they could be prosecuted if they are caught illegally streaming events.
Conor McGregor faces Dustin Poirier in a highly anticipated trilogy fight in the early hours of Sunday morning, with the bout costing €29.99 to buy in Ireland.
The Notorious is hoping to avenge his loss to the American from earlier this year and set up a clash with newly crowned lightweight champion Charles Oliveira.
Speaking ahead of that January bout, Dana White sent a warning to people thinking of illegally streaming the event.
The UFC President told The Mac Life: "We’ve been one of the leagues that has been so proactive on piracy.
"I love how cool and tough this guys act on social media because let me tell you what, we’ve caught a lot of people.
"Let me tell you what they do: they cry. They cry and they beg not to be prosecuted and all this other stuff.

“We just overcame a huge hurdle in the piracy world and we’re going to catch some of these guys in 2021 and I look forward to the crying and the begging. We’ll see how tough they are when they get caught.
He added: “They’re never all going to go away. They’re going to be out there, and we’re not trying to get rid of all of them.
"I just want to catch a few. That’s all I’m looking for.
"You can’t shut the whole thing down, that piracy industry is going to go on forever.
"Let me catch a few and watch what happens — and I will, oh it’s coming."
