John Fury, the father and trainer of Tommy Fury, has called for Jake Paul to “pay up” after a pre-fight bet.
At the final press conference before their eight-round bout last weekend Paul offered Fury a 'double or nothing' deal.
He suggested that if Fury agreed to take nothing if he lost the fight, he would pay him double if he won.

The two shook hands on that bet, though it does not appear that a contract of any sort was signed by both parties.
It was Paul who lost Sunday night's bout on a split decision and, on Wednesday, John Fury, the father and trainer of Tommy Fury, called for the YouTube star to "honour that deal".
Speaking on social media, John Fury sent a message to Jake Paul.
"Moment of truth," he declared. "Again I say it, you lost the fight, we had a deal in front of millions of people worldwide. I expect you to honour that deal. You owe us some money."
He didn't want to be diverted by discussions over a contract. "We were over there to do a job. We did it and I'm sure you'll be a great guy and honour what you've done," John Fury said.
"Pay up!"
