Top Rank's CEO Bob Arum revealed that the rematch between Manny Pacquiao and Jeff Horn, for the World Boxing Organization welterweight title and tentatively scheduled for November 12 in Australia has not been finalized as of yet and there is the possibility now of the second fight heading to 2018.

Back in July, before a crowd of over 51,000 at the Suncorp Stadium in Brisbane, Horn won shocking twelve round unanimous decision over Pacquiao to capture the WBO belt. There is an immediate rematch clause for Pacquiao to exercise.

"Manny is deciding if he wants a rematch this year or next year. If he decides to postpone it, we will make a fight for Jeff in November against a good opponent in Brisbane," explained Bob Arum to ESPN Deportes.

In the coming days, Arum hopes to travel to Manila to get Pacquiao's decision. The eight division champion, now 38 years old, is very busy with his full-time job as a senator in the Philippines.

Regarding Pacquiao's reasons for delaying the fight, tentatively for the first quarter of 2018, Arum said:

"I imagine he has many duties as a senator, he is no longer a young guy and the last fight was very physical, and he may need more time to get ready for a rematch. We'll know in the next few days. "

Regarding the future of Horn, Arum notes that either way he will fight in November against a first-rate opponent, although it would no longer be in the Suncorp Stadium.

"Horn would fight one of the best welterweights and try to do the same kind of business, maybe not the same as he would have done with Pacquiao and we'll have to adjust prices, look for a smaller place, but if Manny can not fight until the next year - we have a young champion and we have an obligation to keep him active," Arum said.
