Boxing analyst Johnny Nelson has claimed that his insight into Tyson Fury‘s preparations for his heavyweight undisputed clash with Oleksandr Usyk came from within the Gypsy King’s family.

The former cruiserweight world champion grabbed headlines when he suggested he had information indicating Fury’s prep for the showdown was not going as planned.

This was followed by the postponement of the bout after the Brit suffered a nasty cut above the eye during sparring.

But Nelson has dismissed theories that he had a secret source within the Fury camp and instead insisted that his opinions came from the information that was publicly disclosed by the boxer’s father John and brother Shane.

‘Do you want to know who the mole is? His dad and his brother – they are the mole,’ Nelson told talkSPORT’s talkBOXING. ‘Because listen, I said nothing his dad hasn’t said.

‘I’ve said nothing his brother hasn’t said, okay I might have sprinkled a bit of seasoning on it, but what I’m saying is it’s on record – his dad was saying the camp’s this, that and the other.

‘It’s on record his brother’s said there’s too many back-slappers there.’

Nelson had told the outlet in February that he had two reliable sources tell him that the heavyweight was having a ‘rough time.’

Fury and Usyk will finally meet in the ring on May 18 as part of Riyadh Season in Saudi Arabia to crown the first undisputed heavyweight champion of the four-belt era.

Nelson continued: ‘Tyson’s not an idiot, but Tyson is the head of the snake – so they’ve all got to behave themselves because they want to stay on that payroll.

‘So they’re going to tell him what they think [he wants to hear] to ingratiate themselves around him.

‘His brother and his dad – they’re his [real] people and they don’t like these people that are around, and they’re not happy.

‘But them people that are around are thinking, ‘”I’m getting paid good, so I’m going to tell you what you want.”

‘I don’t dislike Tyson Fury, I just call out his BS, I don’t dislike him.

He added: ‘Listen to your dad, listen to your brother – they are the ones speaking the truth, they’re the moles.’
