Jake Paul says his upcoming fight with Tommy Fury on 6 August has been cancelled.
YouTuber-turned-fighter Paul, 25, gave Fury until Wednesday to resolve his visa issues.
But he said on social media: “Fury’s received a termination notice. Second time in a row he has pulled out.”
Paul and Fury were originally scheduled to meet last December, but light-heavyweight Fury called off the fight due to a chest infection and broken rib.
Paul says he will now push ahead with plans to fight on 6 August at Madison Square Garden and will announce a new opponent.
“MVP [Most Valuable Promotions] did everything it could to help him and team. He wasn’t interested and he literally went into hiding,” added the American.
“Second time in a row I’m going to step up and take on a new opponent on short notice.”
Fury confirmed on Instagram the fight was off, but said he was “confident” it could be rearranged for a third time.
“I’m gutted and disappointed in regards to the issues I have faced with entry into the USA,” he said. “This is something that myself or my team could have never anticipated happening.
“The situation has been left with my lawyers as being denied entry to a country is obviously a very serious issue and it needs to be subsequently resolved.
“I am confident this fight will happen when this issue gets resolved and we come to a solution. I want to clarify that I will fight in a neutral country that both parties can enter. This can be any time, any place, anywhere.”
