Eight-division world champion Manny Pacquiao's proposed fight against Britain's former world light-welterweight champion Amir Khan has been postponed, according to the Filipino's promoter, Bob Arum.
The 38-year-old Pacquiao and Khan, who won a silver medal at the 2004 Athens Olympics, tentatively agreed to an April fight in the United Arab Emirates before negotiating a change of date to May 20.
