Conor McGregor versus Floyd Mayweather, billed as one of the biggest fights of a generation, is only weeks away as the combatants rev up their preparations ahead of the Las Vegas grudge match.

Favourite Mayweather is looking an absolute physical specimen after a video earlier today showed just how ripped the American is ahead of the fight.

The 49-0 superstar looked calm and confident as he attended what seemed to be a party, taking a break from his brutal training regime.

McGregor has also been pulling out all the stops as he prepares to make his debut in professional boxing.

The Irishman has brought some big names into his camp as he looks to ensure that he will be able to make the swap from Mixed Martial Arts to boxing as efficiently and effectively as possible.

McGregor included hall of fame referee Joe Cortez in his team to officiate over his sparring sessions against some big names, one being former American boxer Paulie Malignaggi. 

Malignaggi enjoyed a stellar career spanning more than 15 years, winning 36 of his 44 fights, seven of which were by knockout, and many saw the move to involve him in McGregor's preparations as a shrewd one.

However, Malignaggi has since left McGregor's camp after the Irishman claimed to have knocked Malignaggi down in sparring, with the American claiming that that was simply not true.

The 36-year-old was unimpressed with the conditions inside the McGregor camp, feeling that the sparring partners were being mistreated.

However, Malignaggi was quick to quash any rumours suggesting that he would or had already spoken to good friend Floyd Mayweather about McGregor when asked during a recent interview.

"No, no, no. I wouldn't do it that way," said Malignaggi, who now works as a commentator.

"I have an ethical side to me. I'm not like Conor McGregor, who, even if I had knocked down McGregor and had a picture of it, I wouldn't post it on social media, let alone Conor, who didn't knock me down, it was a push-down, tries to play it as a knockdown.

"He's trying too hard to sell it for me."

McGregor and Malignaggi have been engaged in a virtual war of words over social media since the incident as the rest of the world struggles to ascertain whose version of events is true. 

What is for certain is that Malignaggi does not think McGregor can beat Mayweather, not even the slightest, but then again, that might just be a bit of sour grapes.
