At the event in Manila, Pacquiao mentioned that Mayweather would fight somebody on December 31 and that he would fight in January in an effort to set up the rematch.
The veteran star clarified matters with reporters during a charity function on Wednesday by dropping the name of his next likely opponent: "Broner, Adrien Broner".
Manny Pacquiao says he'll start training for his 70th fight next week.
Pacquiao said he is 90 percent sure about the Broner fight, his next this year after knocking out Argentine Lucas Matthysse in the seventh round in May in Kuala Lumpur. "After that, we'll know ... he's coming back, we'll discuss it after (Adrian) Broner".
Since then, Pacquiao has defied calls to retire and promised to fight again, prompting unclear reports about a range of possible contenders. About two weeks ago, Pacquiao signed with Premier Boxing Champions founder Al Haymon to become his adviser.
