Matchroom Boxing boss Eddie Hearn has been left "baffled" by Tyson Fury 's recent videos mocking him on social media.
Heavyweight champion Fury announced he would be fighting domestic rival Dillian Whyte next, indicating Anthony Joshua rejected stepping aside from his rematch with Oleksandr Usyk.
Joshua was offered £15million to step aside and allow Fury to fight unified champion Usyk in the first undisputed heavyweight title fight since 1999.
