Did McGregor have an erection at Mayweather weigh in?

Conor McGregor has set the internet alight on Saturday after a very revealing weigh-in ahead of his clash with Floyd Mayweather.

After stripping down to his boxer briefs for the weigh-in, ‘Mystic Mac’, as McGregor is known, left little to the imagination as he faced off with the undefeated boxing legend known as Money.

Muscles were not the only thing bulging during the spectacular stare-down, with veins visibly popping in McGregor’s neck as he screamed in the face of his more composed opponent.

Mayweather wore a special pair of underwear himself – an Irish-green pair branded with PaddyPower and the catchphrase ‘Always bet on black’.

The outrageous display sparked a storm of shocked comments on social media, with some users saying they understood the Irishman’s willingness to walk around in his underwear.

‘McGregor was a little excited during this weigh in,’ said one Twitter user.

McGregor spectacularly defied Floyd Mayweather’s prediction that he would fail to make the weight as they came to the scales before their mega-millions extravaganza.

The Notorious weighed in a full pound under the 154lbs weight limit. Mayweather was significantly but expectedly lighter at 149 1/2 lbs.

That put paid to the notion that his training may have been compromised by late, nightly visits to his strip club. McGregor returned to screaming at Mayweather come the stare down. 

‘He looks like dog s***,’ said McGregor of his opponent. ‘You know that. He looks blown out. Full of water. He’s not going to keep my pace. Trust me on that. That’s the worst shape I’ve ever seen him.’

‘I’m going to breeze through him, trust me on that. I’m a professional, I make weight – its sacrifice, dedication, focus, but I make it. I’m ready.

‘I’m going to be a lot bigger than him tomorrow night, maybe closer to 170.’

McGregor received a boisterous Irish welcome as he entered the T-Mobile Arena draped in his country’s flag and sporting glasses hinged with sun lenses. 

Mayweather responded to his mixed reception by pointing to his white ‘The Best Ever’ baseball cap and T-shirt, smiling broadly and then warning fans of the Irishman: ‘This will be Conor McGregor’s last fight also.’

Mayweather brushed off any potential advantage for McGregor over the size difference though after ending his two-year retirement.

‘Weight doesn’t win fights. Fighting wins fights,’ said the American. 

A sizeable Irish contingent has travelled to Vegas to cheer the 29-year-old in action and he repeatedly saluted his supporters.

‘You can’t beat us, we’ve already taken over what we want,’ said McGregor.

‘Las Vegas is Ireland now.’

Mayweather was not phased by the partisan crowd though – even daring to wear Paddy Power green underwear. 

He said: ‘The fans can’t fight for him. It comes down to the two competitiors.

‘In the 49 times I won out there, it was one on one.’

The two were a stark contrast in their behaviour as they posed head-to-head for the cameras after the weigh-in.

Mayweather was cool, calm and collected as he stared at McGregor, while the Irishman laughed, smiled and launched a verbal assault of trash talk.

It was only when they broke away that Mayweather broke into a smile and laughed at the UFC lightweight champion’s remarks.

But after an undefeated record as a former five-weight world champion, Mayweather stressed how he has been here and done it all before.

‘I’ve been here before. I know what it takes when it’s a fight of this magnitude,’ said Mayweather.

‘I’ve done a lot of this (chatting) he’s done a lot of this, but tomorrow it comes down to the fighters.’
