Kell Brook has inched closer to a quick defence of his IBF weltweight title against Frankie Gavin, according to his promoter Eddie Hearn.
Brook, 28, stopped Jo Jo Dan less than a fortnight ago, but former world champion Amir Khan ignored Brook's offer of a fight at Wembley Stadium in favour of a bout with Chris Algieri.
Khan has since announced that he has not actually confirmed anything with Algieri and is keeping his options open, but Hearn is keen to seal a deal between Brook and Gavin as soon as possible.
Brook's promoter said: "It's not yet a done deal with either Brook or Gavin but it is looking promising for them to face each other at the end of May.
"Gavin could have fought Tim Bradley in America in an IBF title eliminator with the organisation's championship chairman Lyndsey Tucker demanding an answer by the close of play on Tuesday night.
"They have that answer and Frankie won't be facing Bradley as there would not have been any title on the line, just jockeying for position in the world rankings.
"Why take a non-title fight when there is the distinct possibility you can face the world champion anyway?"
Brook would be the heavy favourite if the clash, probably at the O2 Arena in London on May 30, went ahead, but Gavin is prepared to fight his corner.
"I'm not stupid. I'm not delusional. I'm going to have to perform out of my skin," said Gavin.
"But I've definitely got it in me to do it. I'm very confident Kell can be beaten and hopefully it's someone with my skills who will do it.
"Nothing is signed or done yet but I know Eddie's spoken to Kell and Kell's up for it and I'm up for it. So we're going to sit down and have another chat in the next two days and hopefully get it done."
Gavin, who became the first British fighter to win a gold medal at the world amateur championships, was due to face South African Chris van Heerden in Birmingham on May 9 but is now expected to pull out of that showdown.
