A Manny Pacquiao and Floyd Mayweather Jr. rematch is definitely out of the table as the undefeated pound-for-pound great already walked away from the ring, and the Filipino champ's career is drawing to a close.

According to Bob Arum, in an interview with USA Today, per Boxing Junkie, that Manny Pacquiao only has one more fight left in him and that would have to be no later than April 9 because he's running for senator in the Philippines.

With no Floyd Mayweather Jr. rematch on the horizon the Top Rank boss is looking at three possible opponents for Manny Pacquiao: Amir Khan, a rematch with Timothy Bradley or Terence Crawford, who will have to win his match against Dierry Jean on Saturday.

Timothy Bradley should also come up victorious over his match against Brandon Rios come Nov. 7.

Negotiations with Amir Khan's team are still ongoing despite the British boxer saying that he's finding another opponent because the Manny Pacquiao bout is not happening.

With no Floyd Mayweather Jr., a rematch with Manny Pacquiao's nemesis, Juan Manuel Marquez, is reportedly definitely off the table because even if he's the first choice for the Filipino champ, the Mexican is not motivated by money.

"Therefore upping the ante on the money isn't going to do it. And ultimately I think it's the fact the knee hasn't come around 100 percent," he said.

Whoever Manny Pacquiao is facing, Bob Arum thinks that it would be the last fight for one of the Filipino greats.

"I'm happy," he said. "Because one thing that's extraordinarily important given his life plans, is he really wants to be president of Philippines and he really wants to serve the people in the Philippines and he's gotta be able to do it without any kind of impairment to his brain function and the more you stay in boxing, the more you risk that."
