Malingnaggi claimed he had been pushed and later video footage that appeared was inconclusive as boxing and MMA fans took opposing views.

And amid allegations of tampering with the footage, UFC chief White said: "What am I, Steven Spielberg?

"Come on. It's footage of the actual sparring.

"I was there for all 12 rounds and Paulie has said some crazy things, some bad things about me.

"I felt sorry for the guy, it was a one-way beating and a lot of people were saying Conor couldn't box.

Fans have called for a video the full 12-round session to put the dispute to bed.

And UFC president White admitted he was considering another 'leak' but did not want Mayweather to gain an advantage.

He added: "I have no problem releasing the full tape, the problem is that Conor doesn't want Mayweather to see everything that he is doing and everything that he is working on.

"It was very one-sided, it was an absolute beating. And guess what? I think it was the right thing for Paulie Malignaggi to definitely leave for his health's sake!"
