"I'm speaking for myself, but it's a logical thing, and it makes more sense," promoter Fernando Beltran told The Times in a Friday night telephone interview. "It's not official, but I believe it's the fight the fans want more.
"And I know Manny will like the fight for the fans."
Pacquiao was upset in a controversial split-decision for Palm Springs' Bradley on Saturday at MGM Grand in Las Vegas.
Although several veteran fight observers at ringside scored the bout in the 9-3 to 11-1 range in Pacquiao's favor, judges Duane Ford and C.J. Ross scored it seven rounds to five (115-113) for Bradley.
Pacquiao said afterward that he "100%" believed he had won the fight.
While the Filipino superstar does have a clause in the Bradley contract that would allow him to force a rematch for the World Boxing Organization title in the fall, Pacquiao (54-4-2) has engaged in three narrow battles against his rival Marquez.
