Oleksandr Usyk defends his WBC world title against Rico Verhoeven on Saturday in Egypt.
The fight is unusual in location as in nature, with kickboxing world champion Verhoeven getting a title shot in just his second boxing fight – and first since 2014.
The 37-year-old Dutchman is aiming to pull off arguably the biggest upset in the sport’s history.
Ukrainian Usyk, 39, is aiming to continue his near 17-year winning streak.
Will we see an underdog win for the ages or will Usyk’s dominance continue?
BBC Sport asks the boxing world for their predictions.
