Tommy Fury's fight with Jake Paul could go up in smoke ... after TNT claims he was denied entry into the United States ahead of their scheduled press conference in New York.
Just when it seemed like the bout was FINALLY going to happen, Tommy shared the crappy news on his Instagram on Tuesday ... saying his team showed up at Heathrow Airport to hop over the pond ... but they were shut down.
"As soon as I entered the airport, I was pulled to one side and told by a Homeland Security officer that my ESTA had been denied and that I wasn't able to travel to the USA for a reason I apparently know," Tommy said in a video.
