Titled boxing veteran, expert and commentator Carl Froch expressed the opinion that the father of Tyson Fury acted extremely unprofessional during the fight of the Briton against Oleksandr Usyk.
On May 18 in Riyadh, Saudi Arabia, Fury lost to Usyk by unanimous decision of the judges in a fight for the title of absolute world champion in the heavyweight division.
"John Fury's interference in Tyson Fury's corner could have been the deciding factor between victory and defeat. His trainer Sugar Hill knows everything about boxing, he was trying to give him pointers. How can Tyson focus on Sugar Hill's words and follow those instructions when Tyson Fury is yelling in his ear and talking trash through the ropes? It's impossible. You can't listen to two people at the same time.
This could be the difference between winning and losing a close fight. That corner interference could have cost Tyson the fight," BoxingScene quoted Fury as saying.
