British heavyweight Tyson Fury denies that he signed for a rematch with WBC heavyweight champion Deontay Wilder. 

Fury will aim to boost his appeal with American fight fans on Saturday when he faces German underdog Tom Schwarz in his Las Vegas debut. 

Fury is fighting for the first time since his fight against Wilder last December which ended in a controversial twelve round split draw. 

Fury was once a huge undercard when he faces Wladimir Klitschko in November of 2015.  At the time Klitschko ruled the division for over a decade and held four world titles - with Fury outboxing him for a twelve round decision. 

"We've all seen the best heavyweights in the world get chinned now and again don't we? [ Wladimir Klitschko] was the best heavyweight in the world until I spanked him all over Germany," Fury told TMZ. 

"We've seen the best heavyweights in the world get knocked out loads of times or beaten.  We're only men.  We're only human.  And, that's it ... anything can happen in a boxing ring." 

An explosive win on Saturday for Fury will heighten demand for a rematch with Wilder.  The two camps have already tentatively agreed a second fight in early 2020 - but nothing has been signed says Fury. 

"I've signed nothing," Fury says ... "Not that I'm aware of unless someone signed it for me, which is illegal." 

"[Wilder claims that I signed] cause he sucks, that's why ... and he's trying to get some fame off of my back."
