Daniel Geale is set to return in May with Matthew Macklin lined up as his opponent for a big middleweight clash in the United States.
The former unified world champion lost his IBF crown last year to London's Darren Barker in one of the best fights in 2013, but returned to winning ways when beating Garth Wood in February.
Geale, 33, admitted through his Twitter that talks were underway and an announcement should be made soon.
"So, my next fight is in the making against Matthew Macklin in the US on May 24th....keeping focused. Management are finalising negotiations and expect to make an announcement shortly," he said.
The 33-year-old has been a top middleweight for the last three years since defeating Sebastien Sylvester in Germany for the IBF title. Going on to defeat Felix Sturm and Anthony Mundine during his reign, the Australian defended his title four times before losing to Barker on a split decision.
Macklin is a top ten middleweight himself. Having lost three of his last six bouts, two defeats have come against top 10 pound-for-pound ranked fighters in Gennady Golovkin and Sergio Martinez - who faces Miguel Cotto in June.
Now 31-years-old, the Irishmen was lined up to face Andy Lee in an all-Irish affair but with Lee moving down to 154lbs, that's been scrapped for now.
Macklin won his last bout against Lamar Russ in December, and a win could see him challenge Sturm for a second time with the German currently holding the IBF belt.
A win for Geale would also see him move into contention to challenge the 34-year-old Sturm.
