Manny Pacquiao and Juan Manuel Marquez are set to fight for a fifth time in September but the bout is unlikely to take place in the US for tax reasons.
Pacquiao had won twice and drawn once in his three previous meetings with Marquez.
All four of their past meetings have been in Las Vegas but the next fight is likely to be in Asia according to Pacquiao's representative Rose Tamayo.
"The fight is definitely in September. We will talk about the opponent and the place after the 13 May elections," she said.
"Manny wants to fight outside the United States because of the taxes. Singapore is one of the top places for consideration. There is also Macau and Dubai."
While Marquez was not named as the opponent, it is common knowledge that Top Rank promoter Bob Arum is looking to make the fifth fight happen.
The location could be an issue though. Marquez has only fought once outside of North America – when he lost a unanimous decision to Chris John back in 2004 in John's native Indonesia.
