Tyson Fury and Deontay Wilder will do battle in their highly anticipated trilogy tonight in Las Vegas for the WBC and Ring magazine championship belts.
American Wilder is seeking revenge against Fury, who clinched the heavyweight championship for a second time with a 7th round TKO when the pair last met in February 2020.
The third fight was originally supposed to take place last summer, but had to be postponed after Fury tested positive for COVID-19 in July.
Tensions have flared in both camps during the build up, and the scene is set for an explosive night of boxing.
