The video of Conor McGregor ’s controversial sparring session with Paulie Malignaggi has been released ahead of the UFC star’s boxing debut against Floyd Mayweather later this month.

The Irishman goes 12 rounds – or less, if you are to believe either fighter’s knockout predictions – with his American rival in Las Vegas on 26 th August.

But his preparations for the superfight hit a speedbump last month when Malignaggi, who was drafted in by McGregor as a sparring partner, stormed out of the camp after photographs emerged of him on the canvas, implying he had been knocked down.
