Plans for Darren Barker remain fluid as promoter Eddie Hearn chases a big fight for the Barnet middleweight.
Barker has put an injury nightmare behind him to win his last two fights via fourth round stoppage, and currently holds the IBF inter-continental belt.
However, world title fights are on the 30-year-old's horizon if Hearn can get the deal done.
"We are still speaking to Top Rank regarding Julio Cesar Chavez Jr, Barker and Brian Vera are on the shortlist although I expect Martin Murray to have popped into the equation," he told Sky Sports.
"We spoke to Gary Shaw about the possibility of Darren fighting (IBF champion) Daniel Geale, in which they're interested and going to come back to us about the possibility of that happening this year.
"Darren's ready to go and we can keep him ticking over in Hull (July 13) or on the Haye show (June 29). But Darren has to have a big fight very soon and I'm working hard to deliver that.
"He's put himself back in the picture and people are talking about him again -it's a good time for Darren. If I can't secure him a world title fight abroad he'll be fighting in London in September in a major fight."
