Promoter Eddie Hearn of Matchroom Sport is hoping to seal the deal on a welterweight grudge fight between Amir Khan (31-4, 19 KOs) and IBF welterweight champion Kell Brook (36-1, 25 KOs).

For the last few years, Brook has chased after the fight with Khan having little to no interest in the fight. But for the first time Khan is actively involved in the discussions and appears to be serious about facing Brook.

According to Hearn, both sides are discussing the fight and things are going very well at the moment. He hopes to have the fight finalized by the end of January.

 At the moment Hearn is negotiating with Khan's advisor Asif Vali.  

"There is still a way to go but it's the obvious fight and talks are positive about finally making this a reality," Hearn told Sky Sports. "We are working hard behind the scenes with Asif Vali to try and get the fight over the line and hope for some good news in middle to late January."

Both fighters are coming off stoppage defeats in catch-weight bouts. Khan went up to 155 to face Saul 'Canelo' Alvarez in May at the T-Mobile Arena in Las Vegas and was knocked out in six rounds. Brook went two divisions up to fight Gennady Golovkin for the IBO, IBF, WBA, WBC middleweight belts and we stopped in five rounds.

Both fighters are coming back from injury. Brook suffered a fractured orbital bone in the loss to Golovkin and needed surgery afterwards. Khan has two surgeries on his right hand to fix an ailing injury that affected him for the last few years.

The big angle is Brook's mandatory obligation to Errol Spence. The IBF does not allow step-aside deals, so Brook will either have to face Spence in the interim and then go on to Khan, or vacate his title. Khan wants to take an interim-fight in April.
