"People want to see Conor fight in MMA. That's what they want to see. Listen, the Mayweather thing was a one off f***ing crazy deal but this is where he belongs. This is the sport he is in. This is the sport he excels in and he's the world champion. This is where he needs to be.
"Let me ask you a question. Why did Paulie Malignaggi get up and walk out of camp after two sparring sessions? Because it was the right f***ing thing to do. Because he was going to get hurt. Because he was gonna take damage that would affect him for the rest of his life that he didn't need to f***ing take.
"It's not like they were paying him big money or he had a f***ing fight coming up himself. Paulie Malignaggi got up and left camp and he f***ing should have got up and left camp because Conor was going to f***ing hurt him badly.
"It's no disrespect to the guy. It's a f***ing fact. I was there. I watched the f***ing whole sparring session. That guy needed to go home and he needed to leave Las Vegas and not go through another of those sparring sessions."
White, who released two video clips of the sparring session, has also poured cold water on a McGregor vs Nate Diaz trilogy fight - meaning all signs are pointing towards the UFC doing the right thing and having the lightweight champion face the interim 155-pound champ Tony Ferguson.
While Ferguson just won the interim belt with a submission win over Kevin Lee, McGregor claimed the main strap way back in November last year, when he took a historic knockout win over Eddie Alvarez at Madison Square Garden.
