Saturday’s bout has a weight limit of 154 pounds, one that Mayweather has never exceeded in his career. The UFC star is the naturally bigger fighter, standing an inch taller than the undefeated boxer with a two-inch reach advantage. When the first-round bell rings Saturday night, McGregor could have a significant weight advantage, as well.

“I just don’t know if he’s used to fighting guys that do big weight cuts,” trainer John Kavanagh, who will be in McGregor’s corner, said on “The MMA Hour” earlier this week. “That doesn’t seem to be as big a thing in boxing. Mayweather seems to pretty much be at walking weight at 150, 151, something like that. Conor’s about 170, so it’s a big, big difference.”

Mayweather, however, has been in a similar situation before. He retained his light middleweight title against Canelo Alvarez four years ago at a catch weight of 152 pounds. Alvarez was 15 pounds heavier on fight night, unofficially weighing in at 165 pounds. Mayweather put on a masterful performance and cruised through 12 rounds for the victory.

Mayweather first won the light middleweight championship 16 months prior to beating Alvarez. He weighed in at 151 pounds when he defeated Miguel Cotto for the 154-pound championship in 2012.

McGregor fought exclusively at 145 pounds in the UFC until he won the featherweight championship in 2015. He jumped up two divisions for a fight against Nate Diaz on March 5, 2016, weighing in at 168 pounds for both his loss at UFC 196 and his victory in the rematch five months later. McGregor’s last fight came in November when he weighed in at 154.4 pounds before beating Eddie Alvarez for the UFC lightweight title.

Mayweather believes that the weight limit could cause more problems for McGregor than himself. He indicated to Ariel Helwani of MMAFighting.com that the underdog might be having trouble making 154 pounds.

“From what I was told, I’ve been doing my homework and I’ve been hearing a lot about he’s been getting IV bags,” Mayweather said. “I don’t know if it’s true. I’m just saying rumors. I heard he got like seven IV bags, and with the Nevada commission, that’s illegal. That’s what I was told. I don’t know if it’s true.”

Mayweather said he’ll have no trouble making weight.

“I weigh like [1]53, [1]52. I ain’t worried about that,” he said. “I could eat a Big Mac, eat a Whopper, something like that. I might eat some pizza.”

UFC president Dana White told TMZ that Mayweather’s claims about McGregor using IV bags are false.

If Friday’s weigh-in is anything like the last time McGregor fought in Las Vegas, it should be pretty eventful. McGregor was ultimately fined $25,000 by the Nevada State Athletic Commission for throwing a water bottle at Nate Diaz during a UFC 202 press conference.
