Lennox Lewis suspects Tyson Fury will only walk away from boxing once he has cemented himself as the number one heavyweight of his era – by beating Oleksandr Usyk and Anthony Joshua.
Fury (31-0-1, 22KOs) has repeatedly suggested he will retire after his WBC heavyweight title defence against Dillian Whyte in an all-British affair in front of around 94,000 spectators at Wembley Stadium on Saturday.
