Oleksandr Usyk 's sparring partners have been "sent home" after failing to keep up with the Ukrainian as he prepares for his heavyweight world title rematch against Anthony Joshua.
Usyk makes the first defence of his heavyweight belts against Joshua on August 20 in Jeddah, Saudi Arabia. Both men haven't fought since their first meeting last September, when Usyk outclassed Joshua to become a unified heavyweight champion in just his third bout at the weight class.
Nursultan Amanzholov, an undefeated Kazakh heavyweight prospect, has been sparring with Usyk and his manager, Aamir Ali, revealed that the Ukrainian has been pushing the paces on his training partners, with many of them failing to keep up.
