Tyson Fury believes his dad John would knock out Eddie Hearn in one round if the pair fought on his undercard.
After his father posted a picture of his body transformation last month, Fury joked he could appear on the undercard of his world title fight against Dillian Whyte in April.
Fifty-seven-year-old John retired from boxing over 25 years ago after suffering consecutive knockout losses and finishing his career with a record of 8-4-1.
