Imagine if Fury vs Whyte falls apart a week before and Frank Warren has to insert the substitute he already has ready.
There's a difference. Whatever you make of Ticketmaster, Warren uses them as a supplier of services. Hearn uses StubHub whilst also accepting them as a sponsor. We will never know the commercial arrangements - maybe there's nothing in it. But that's why Warren brought it up in the first place.
It is a very poor card with a poor headline fight as Whyte is simply a younger version of Chisora. Zero threat to Fury and a disgrace of a card.
Fury v Weak Opponent does not have the same excitement as the three huge fights with Wilder. Probably will still sell very well as Fury is a huge star in the UK with a huge fanbase.
