There is fuck all chance this fight will be on Sky Box Office. For what Fury is worth he nor Klitschko are PPV standard fighters in the UK it would flop. So I wouldnt be shocked if it was on normal Sky. Saying that I am guessing if AJ is on the undercard which Hearn was hinting at him and Hennessy might do a deal for Sky over the others mentioned. ITV have been lucky so far since they got back in with Carl Frampton his average ratings were good. For his Avalos fight he pulled in 1.9 million people for the fight Saturday gone he pulled in 2.4 million people from ITV alone. They are also claiming from the 4 stations alone that covered the fight his last fight was watched by close to 5 million people not too bad going for Frampton.
Also I think ITV if they get into boxing again they could well bring back the glory days of Naz when he was fighting on there. Could you imagine what they would pull in for a Brook v Khan fight on ITV huge numbers. Sadly those fights wont happen on free to air tv.
