It would be on PPV if it were to happen. Sky Box office most likely, although Tyson Fury has signed a deal with Frank Warren who works with BT Sport, they have their own PPV channel ready to go so maybe they'd want to host it. It would probably make the most money on Sky. They're quite slick at promotion and they have a ready made audience. Doubt it will happen though. Fury will not take any risks prior to an AJ fight.
