Honestly get a program that lets you act like you are on a browser in the U.K. And watch all the fights free online or whatever. The mcgregor mayweather fight was like 20 bucks if you were in the U.K....
A little too late, but for the Mayweather fight I went to Twitter and searched "mayweather periscope" and found a stream. Might take a few streams to find one that has good enough quality to watch, but it beats paying $$$
I went to Instagram and someone had it on their live feed and "Bud" Crawford is the real deal. I can't wait until he moves up to welterweight. Some great fights there for boxing.
