Tyson has already landed the first blow, slapping Paul at their pre-fight weigh-in.

Here's everything you need to know.

Did Tyson slap Paul?

Tyson most certainly slapped Paul at their pre-fight weigh-in.

After stepping on the scales, the antics started with Paul crawling up towards the traditional face-off for the cameras with Tyson.

As he rose up right into Tyson's grill, the former heavyweight champ took exception to something — or was sick of Paul's schtick, or was play-acting to a promotional script — and slapped Paul across the chops.

"I didn't even feel it," Paul said.

"He's angry, he's an angry little elf. Mike Tyson, I thought that was a cute slap, buddy, but tomorrow you're gonna get knocked the f*** out.

"I'm f***ing him up. He hits like a bitch. It's personal now. He must die."

How do Tyson and Paul compare?

Tyson and Paul got on the scales on Thursday, local time, with both needing to top 200 pounds (90.7 kilograms) to qualify for a heavyweight fight.

Paul weighed in at 227.2 pounds (103kgs), and Tyson at 228.4 (103.6kgs).

Paul has won 10 of his 11 sanctioned bouts since 2020, while Tyson has a 50-6 record from his 20-year professional career, and was the youngest heavyweight champion ever.

How old is Mike Tyson?

Tyson will be 58 years old when he ducks under the ropes to face 27-year-old Paul.

Tyson was just 20 when he knocked out Trevor Berbick to win his first heavyweight world title way back in 1986.

This is his first professional fight since losing to Kevin McBride in 2005, although he did fight fellow retired champion Roy Jones Jr in late 2020.

What are the rules?

There have been a lot of questions asked over how this fight, with the biggest age gap between participants in boxing history could be officially sanctioned.

The hope is that a shorter fight with shorter rounds — eight two-minute rounds rather than 10 or 12 three-minute rounds — will make it less taxing.

The fighters will also wear 14-ounce gloves (396 grams) instead of the traditional 10-ounce mitts (283 grams).

Why are they using heavier gloves?

The theory is that the heavier gloves can't be swung as quickly and the extra padding softens the blows, reducing damage, but the opposite has also been argued.

"The glove size means nothing," boxing promoter Lou DiBella told USA Today when asked about the bout.

"Does nothing to soften brain blows; some argue that the bigger mass creates more contact and more ricochet effect of brain moving."

Who is on the undercard?

There are six fights before Tyson and Paul, including a massive rematch between Katie Taylor and Amanda Serrano for the unified lightweight world titles.

The pair's first bout was named fight of the year in 2022 by Sports Illustrated and The Ring, with Taylor winning a 10-round split decision.

Australian Dana Coolwell is also in action to start the night, taking on American Bruce "Shu Shu" Carrington.

The other fights include:

• Lucas Bahdi vs Corey Marksman
• Shadasia Green vs Melinda Watpool
• Neeraj Goyat vs Whindersson Nunes
• Mario Barrios vs Abel Ramos
