Not that long ago Fox Sports and Fox Sports Plus used to show championship games in the States, and they were pretty reliable - once they listed a match they would show it. Now that BeIn and, for a time Gol TV, have taken up the slack it's been a lot more iffy.
Just looked at the Live Soccer TV / BeIn Sports Connect link again and it is showing the Brighton and Millwall games – but I will be checking with Nevada Smiths before I head off Saturday morning!
Nevada Smiths in NYC is screening it live - so it seems some footie bars do have access to the internet stream
