I've just been reading a bit more about this and it looks like only good news for UK fans. The 16 US shows are all being broadcast on Sky, and all the of the cards are starting at 1800 US time- so New York shows will start at 2300 here! Even Vegas shows will begin at 0200, so much improved. They also provide Sky with 16 domestic fights a year too, so we get 32 cards a year from Matchroom. They are going to need an awseome stable and it looks like Terence Crawford might well be one of the first to join.
You have to give Hearn credit, if he pulls this off he will essentially run boxing- and he seems to be using mainly risking Perform Group's and DAZN's money rather his own to do so.
