It is a brilliant match
The heavyweight division has been longing for a fight to excite and Stiverne's WBC title defence against Wilder ticks all the boxes.
The judges are unlikely to be needed
Wilder has a 100% KO record in 32 fights. Stiverne has knocked out 21 of his 24 rivals. Do not blink.
Toe-to-toe tear up
It is puncher v puncher! When both men fight they only know how to steam forward. Wilder fights on fear and when Stiverne gets caught he looks to throw heavy shots back.
Does Wilder have a chin?
Plenty of people doubt his whiskers. He was floored by Harold Sconiers before winning in the fourth round back in October 2010. In 2007 Stiverne battered Sconiers inside a round.
Wilder could become a star
If Wilder triumphs he is likely to become a mainstream attraction. He doesn't just shoot from the hip with his fists. The US ace fires from the lip and knows how to talk and sell a fight.
Can Stiverne or Wilder challenge Wladimir Klitschko?
WBA, IBF and WBO champion Wladimir is one of the most dominant heavyweights of modern times. Nobody seems close to beating him, but can Stiverne or the Bronze Bomber show something to suggest they're a threat?
Will Stiverne be ring-rusty?
This will only be Stiverne's third fight since he beat Willie Herring in April 2012. Wilder has boxed 11 times since then.
There hasn't been an American world heavyweight king since Shannon Briggs won the WBO crown for a few months from November 2006. There is pressure on Wilder when he takes on the competent Haiti born champion.
We will find out if Wilder is a contender to be the best or a pretender
The first big world title fight of 2015 has got everybody talking. The main debating point is whether Alabama man Wilder is the real deal or someone whose hype is louder than his bite. We're about to find out.
Big-time heavyweights are back in Las Vegas
The last heavyweight title fight held in Sin City was Oleg Maskaev's 12th round win over Hasim Rahman in August 2006. The WBC title was at stake.
