Mixed martial arts star Conor McGregor will carry a sizeable weight advantage into his superfight with Floyd Mayweather after tipping the scales nearly four pounds heavier than the boxing legend here on Friday.
Irish star McGregor - who had been accused by Mayweather of struggling to make the 154-pound limit - weighed in comfortably at 153 pounds in a raucous face off at the T-Mobile Arena.
Former welterweight king Mayweather, 40, meanwhile came in at 149.5 pounds.
McGregor, 29, is likely to bulk up substantially before Saturday's 12-round bout, meaning Mayweather will be several pounds lighter than the two-time UFC world champion.
"That's the worst shape I've ever seen him in. Trust me on that," McGregor roared after the weigh-in.
"I'm a professional, I make weight, that's dedication, that's focus. I'll be a lot bigger than him tomorrow, closer to 170," he added.
A nonplussed Mayweather meanwhile shrugged off his likely weight disadvantage and once again vowed to stop McGregor inside the distance.
"I've been here before. I know what it takes for a fight of this magnitude," Mayweather said.
"Weight doesn't win fights, fighting wins fights. It won't go the distance. Mark my words - I'm not worried about the scales."
