Either Deontay Wilder or Tyson Fury will end the night as an undefeated WBC and lineal heavyweight champion, whilst the other will lose their undefeated run. However both men will end up significantly richer.
The heavyweight division in boxing has always been the most prestigious but the last few years has seen some of the allure dampen without enough big names or high profile fights.
Now though the division is back to where it belongs, front and centre of all the attention and Deontay Wilder vs Tyson Fury is one of the biggest fights in the last 10 years in the division, with only Fury's fight with Klitschko and the Ukrainian's with Anthony Joshua for company.
The fight sees two undefeated boxers fight for the WBC and lineal championships and will cement the winner as the best heavyweight in the world.
The Bronze Bomber's power makes him the favourite, especially with the Gypsy King only three fights into his comeback, but the Brit cannot be ruled out.
Wilder is the 'A side' as the current holder of the belt but both men are set to be paid handsomely. According to the California State Athletic Commission, via ESPN, Wilder's purse is $4 million whilst Fury's is $3 million.

Both men will earn more than that once they've taken their slices of the pay-per-view pie and their cut of the ticket sales but it's a bloody good start.
Interestingly further down the card Jarrett Hurd, who will defend his light middleweight titles, is earning $1 million but opponent Jason Welborn, from England, will earn just $30,000.
The other Brit on the card, Joe Joyce, will earn $40,000 for his fight against Joe Hanks, who will take $50,000 home.

No matter how much he earns Fury has vowed to hand the cash over to charity to help the homeless, recently saying, "I'm going to give it to the poor and I'm going to build homes for the homeless.
"I don't really have much use for it, I'm not interested in becoming a millionaire or a billionaire.
"I'm going to give it to the poor and I'm going to build homes for the homeless. I'm a boxer not a businessman and I'll probably go down the same route as every other boxer skint at the end of it all."
If he can follow up those classy words with as classy a performance in the ring then he'll soon by world heavyweight champion once again.
