CHRIS EUBANK Junior has missed out on a multi-million pound fight with Gennady Golovkin.

Golovkin will defend his IBF, WBA, WBC and IBO Middleweight World titles in Britain this year – but not against him.

Brighton’s Eubank Jr, 26, had been expected to sign a deal to face the middleweight king this week but Eddie Hearn’s Matchroom Boxing have announced IBF Welterweight champion Kell Brook will meet the US-based Kazakh dubbed GGG at The O2 in London on September 10.

Hearn, who represents both Eubank Jr and also Sheffield fighter Brook, has claimed Team Eubank missed the deadline to sign the contract for the fight.

Brook will move up two weight divisions for the fight.

Eubank Jr, son of former two-weight world champion Chris Eubank senior, responded on social media to the announcement by tweeting: “I haven’t been shown one contract since my fight with GGG was announced. I’m still ready & waiting to sign. Fighting Brook is a joke #2Small”

Hearn claimed Team Eubank wanted too much operational control over the show.

He said: “I said this is the deal. It’s the same pay-per-view deal as Anthony Joshua, the same as Carl Froch, you own the show, you own the money but we are the promoters, it’s our licence, our brand and our image that we have built up over 30 years of promoting boxing.

“They were given to 5pm and they did not come back to me.”

He added: “They have got their own ideas how things work so you can’t blame anyone but we don’t work like that.

“We have standard format for all pay-per-view fights, which is hugely lucrative and he would have made millions of pounds, but Chris Eubank senior was being extremely difficult.

“I wasn’t calling their bluff when I told them there was a deadline to make the fight.”

Golovkin, 34, steps into the ring as a defending champion for the 16th time in his first fight in the UK.

Brook said: “You get fighters saying they want to fight the best but they don’t step up to the plate.

“Eddie (Hearn) put this to me 24 hours ago and I said yes straight away. Everybody is running away from Triple G but I am running towards him. I want these big fights.”
