Boxing has a bustling heavyweight division and two of its marquee attractions, Deontay Wilder and Tyson Fury, contest a high-profile rematch in Las Vegas on Saturday.

Wilder, Fury, and 10 other heavyweights have been ranked by Business Insider ahead of the MGM Grand Garden Arena showdown.

Joining America's heavy-hitting fighter and Britain's unpredictable boxer in this list are Anthony Joshua, Dillian Whyte, and Andy Ruiz Jr., who have all had good wins of late.

Then there are rising stars Michael Hunter, Oleksandr Usyk, and Adam Kownacki.

Record: 31 wins 26 KOs against 2 losses 2 KOs .

Biggest wins: Bryant Jennings, Tony Thompson, and Malik Scott.

At 40, Luis Ortiz's better days may be behind him, but he showed in his most recent bout, a 2019 knockout loss to Deontay Wilder, that he can still compete at a high level.

Ortiz was doing everything right in that fight, winning every minute of every round until bang, he was knocked out by Wilder's right hand.

11: Kubrat Pulev Bulgaria.

Record: 28 wins 14 KOs against 1 loss 1 KO .

Biggest wins: Alexander Dimitrenko and Tony Thompson.

Kubrat Pulev's only loss was a resounding defeat to Wladimir Klitschko in 2014.

Since then, he has gotten himself into a mandatory challenger situation, and will likely fight for Anthony Joshua's world titles in the summer.

10: Oleksandr Usyk Ukraine.

Record: 17 wins 13 KOs , unbeaten.

Biggest wins: Mairis Briedis, Murat Gassiev, and Tony Bellew.

The way Oleksandr Usyk cleared out the cruiserweight division was truly a sight to behold.

The 33-year-old left the 200-pound weight class in 2018, but has fought only once since then, an uninspiring win over Chazz Witherspoon at heavyweight in 2019.

It is unclear when he will fight again, but if he is to climb this ranking he will need to take on other ranked fighters, and win.
