World heavyweight champion Oleksandr Usyk addressed his next opponent Tyson Fury, urging him to work on his fitness.
"He and I have a contract until December 31; we have to make this fight before the end of the year. If he backs out of the fight on Dec. 21, he will lose all his money and dividends and will no longer be a man of his word.
"You put the mask on and start running. You only attack the little guys, don't you? How are you doing, my chubby buddy? I hope you're okay and come out fighting."
