British boxer Tyson Fury (34-1-1, 24 KOs) reacted to a video posted by his opponent, WBA, WBC, WBO, and IBO heavyweight champion (over 90.7 kg) Oleksandr Usyk (22-0, 14 KOs) of Ukraine.
"My friend, Tyson Fury, I’m ready for December 23. Are you ready?" Usyk said in the video.
"On December 23, you’ll still be broken, little man," Fury wrote in response.
In May, Oleksandr Usyk defeated Tyson Fury by split decision, becoming the first undisputed heavyweight champion (over 90.7 kg) in 25 years. The rematch is scheduled for December 21 in Riyadh, Saudi Arabia.
