Promoter Eddie Hearn of Matchroom Sport, who promote British middleweight champion Chris Eubank Jr. (22-1, 17 KOs), says a deal is nearly complete for a September fight with IBO/IBF/WBC/WBA middleweight world champion Gennady 'GGG' Golovkin (35-0, 32 KOs), on a date in September in the UK.

Hearn has been speaking with Tom Loeffler, who promotes Golovkin, and both sides have agreed to most of the details related to the fight.

Discussions for the contest heated up after it was revealed on Wednesday that Mexican superstar Saul 'Canelo' Alvarez would not face Golovkin until the fall of 2017 at the earliest.

Eubank is scheduled to return on Saturday night, when he faces undefeated Tom Doran (17-0, 7 KOs) at the O2 Arena in London. The fight will be part of the Anthony Joshua vs. Dominic Breazeale undercard.

Hearn reveals that contracts have been drafted and soon both sides will face the moment of truth - signing the actual papers to fight each other. The venue is known. Hearn is more interested in wrapping up the deal and then he's evaluate the options of where it should take place.

"There have been lots of conversations with Tom Loeffler, contracts drafted, terms virtually agreed. And obviously Eubank has his own fight to take care of on Saturday night. And Although he's a strong favorite he shouldn't overlook Tom Doran. I had a good chat with him yesterday and it's a big opportunity for him. There are a few things to tie up, but basically if everyone really wants the fight it's there for you to sign," Hearn said to Sky Sports."

"If Golovikin really wants it and I believe he does. If Eubank really wants it and I believe he does. There is a good chance of that fight taking place in London. I think it's a stadium fight. Let's get the ink dry and then decide if we want to take the risk outdoors."
