Chris Eubank Jr's father has abandoned him for the jungle, claims Spike O'Sullivan

Spike O'Sullivan says Chris Eubank Jr's father has abandoned him ahead of their WBA middleweight title eliminator at the O2 in London on December 12, live on Sky Sports Box Office.

Eubank Sr missed the first press conference for the fight as he went to Australia to take part in the 'I'm A Celebrity…Get Me Out Of Here' television programme, which does not finish until this Sunday.

Irishman O'Sullivan believes Eubank Sr has chosen the reality show over the biggest fight of his son's career, and that will be a costly mistake when they meet on December 12.

"The fact is, his dad chose to go to the jungle and eat animal genitals over being here with his son," said O'Sullivan.

"I think it has been to Junior's detriment that his father has not been here for the build-up. He's not used to being without his old man. I think he's a lost little child without him and when we get in the ring it will be something similar.

"He's starting to sound like his old man. He's becoming more eccentric day by day and 99 per cent of what comes out of Chris' mouth is absolute rubbish, he's deluded.

"His father has deserted him yet again, he doesn't give a damn about him. He's prepared to put him in the ring and doesn't care what happens to him as long as he makes money. It's sad to see."

O'Sullivan's clash with Eubank Jr is part of a huge night of action at the O2, topped by Anthony Joshua taking on bitter rival Dillian Whyte for the British and Commonwealth heavyweight titles.
