YouTube star turned professional boxer Jake Paul accused British boxer Tommy Fury of trying to seemingly back out of their fight on Aug. 6 after Fury revealed on Tuesday that he was denied entry into the U.S. for a pre-fight press conference.

Paul, who is 5-0 in his career with four knockouts, took to Twitter to call out Fury over what he called his "latest excuse."

"Tommy, no matter how hard u try to get out of this fight, I’m going 2 do everything in my power 2 not let u weasel ur way out," he wrote. "My team & my partners have made it clear the steps u need to take 2 solve ur latest excuse."

Furry, who is 8-0 with four knockouts, took to Instagram earlier to explain that he was stopped at Heathrow Airport and told that his visa had been denied, adding that it was a "massive shock" to his whole team.

"I was told by the homeland security that my ESTA (US Electronic System for Travel Authorization) had been denied, and I wasn’t able to travel to the USA for a reason that I apparently know. I can stand here and say I’ve done absolutely nothing wrong, and I have no clue why I’m not allowed to travel to the USA," he said in his Instagram Stories.

"I don’t know why this has happened today, it’s a massive shock to me and my whole team. Obviously, it’s a matter that needs to be resolved. It’s government issues. It’s a lot bigger than the fight right now, and I’m just trying to get it solved, but I just wanted to let you all know where it was at."

Law enforcement sources told TMZ Sports that the issue has to do with Fury’s ties to a suspected crime boss.

Paul’s production company, Most Valuable Promotions, released a statement on social media saying Fury was in the U.S. a month ago and was "surprised" to learn about his visa issues.
