Frank Warren, promoter for light heavyweight prospect Tommy Fury, is holding out hope that everything can worked out for a planned fight against Youtube star turned boxer Jake Paul.

The fight is scheduled for August 6th at Madison Square Garden in New York City, as the main event of a Showtime Pay-Per-View card.

Last week, Fury was denied entry into the United States. He was turned away at London’s Heathrow Airport due to his ESTA (Electronic System for Travel Authority) document being denied, which prevented him from attending a planned press conference to officially announce the pay-per-view fight with Paul.

Paul has given Fury a deadline of Wednesday morning to sort the matter out - with three backup opponents already lined up.

"Tommy is officially out by Wednesday morning if he doesn’t go to the embassy / come out of hiding. Three other opponents lined up. I’m built different," Paul stated on social media.

They were initially scheduled to fight in December. Fury withdrew with an injured rib and a chest infection. He was replaced by former UFC champion Tyron Woodley, who was brutally knocked out by Paul.

Older brother, WBC heavyweight champion Tyson Fury, is reportedly not allowed to enter the United States - due to alleged drug cartel leader Daniel Kinahan being his adviser for several years. And, John Fury, Tommy’s father and head trainer, is not allowed in the United States due to a criminal conviction from 2011.

Tommy is still not sure why he was denied entry, but apparently the matter in not related to Kinahan.

Warren wants his boxer to go to the United States Embassy to work out the matter as soon as possible - before Paul goes in another direction with a new opponent.

"He [Tommy] has got to get to the Embassy, but no appointment has been made yet. I can understand where they're coming from. They've got a show to run or whatever and if we can't get it sorted out then obviously they'll go to another opponent so we'll just keep working on it and trying to make it happen," Warren told IFL TV.
