It really isnt a very big fight in the UK Due to the fact that BJS isnt at all well known amongst the casuals, who form the vast majority of boxing fans It isnt on in the evening at prime time and BJS isnt a PPV fighter. He also isnt generally that loved because of some of his out of the ring antics. With the time it is on, I cant think that many British fight fans will be watching Only the hardcores will be watching at 5am in the morning UK time
How many Mexicans are there in the UK? I just googled the number: 9,771. That's the answer to the thread question.
It doesn't involve AJ, Whyte, Chisora, Eubank Jr. or Khan, so the British and media will have little interest in it.
