Logan Paul and Floyd Mayweather will weigh in for their exhibition bout tonight.
The pair will fight at the Hard Rock Stadium in Miami tomorrow night and will step on the scales later today along with the rest of the card.
There will likely be a 30lb disparity between the two when they face off, with Logan Paul allowed to come in at 190lbs, while Floyd may only go up to 160lb.
However, that weight discrepancy will be evened out by an absurd skill differential, with 0-1 professional Paul expected to be handily dispatched by 50-0 Mayweather.

And Mayweather and Paul will follow at 11.45pm.

Quotes
Logan Paul: "We’re prepared for anything. We did a legit proper camp. We’re doing hard sparring rounds, 10-12 rounds, three different guys, we’re ready.
"We’ve got a group of pros [to spar with], some guys are brawlers, some guys are boxers. We try to get guys who can emulate Floyd, or at least keep the pace for small guys.
"Honestly every look we can, we get: pros, solid, solid boxers. I sparred a couple of times, [WBA light-heavyweight champion] Jean Pascal, who is on the undercard actually. It’s great work, tough guy."
Floyd Mayweather: “My nickname is 'Money' for a reason," he said. "I believe in working smarter, not harder.
"So if it's something easy like a legalised bank robbery, I've got to do it. I have to do it.”
