Duco's Dean Lonergan is negotiating with the Queensland Government to promote a WBO title fight at Suncorp Stadium in April, but his mission is mired in confusion over who is in charge in Pacquiao's corner.
Long time Pacquiao's promoter Bob Arum is an ally of Duco, but another Pacquiao Advisor, Canadian Michael Koncz, said over the weekend the fight will take place in the United Arab Emirates.
However News.com also reported Koncz as saying there is "no war" between the Pacquiao handlers.
"Manny has made it clear that he will end his career with Top Rank," Koncz said.
"We all know about Bob's contribution to Manny's career and Manny knows that. There is no bitterness ... no war involving us."
And not everyone is in the Pacquiao-Khan corner.
Irish boxing legend Barry McGuigan said Khan was not in the right frame of mind to take on Pacquiao, after a big loss to Mexican Canelo Alvarez.
"...we saw when he stepped up from welterweight to middleweight to fight Alvarez the dangers of biting off more than he can chew," McGuigan wrote in the Daily Mirror.
"And, given the high-profile turbulence in his private life recently, I'm not sure that kind of publicity is conducive to taking on Pacquiao."
