Manny Pacquiao's trainer Freddie Roach has already expressed his willingness for a rematch.

"I thought we fought a good fight," said Roach. "We'd love to do it again. Hopefully as soon in the future."

However, Floyd Mayweather seems not interested to do a rematch with Manny Pacquiao as he said: "I can quit boxing today and I'm a-okay. In my era, I'm TBE (The Best Ever)."

Meanwhile, the Reuters reported that Manny Pacquiao is "likely to face disciplinary action for failing to disclose a pre-bout shoulder injury."

The team of Pacquiao has not disclosed the information to the Nevada Athletic Commission regarding the shoulder issue until the couple of hours before the "Fight of the Century."

"The first I heard of this was at 6:08 (p.m. PT) when he arrived in the locker room. I have no proof of the injury. If he told us on Friday, we would have gotten the MRIs and there are a lot of things we could have done," said commission chairman Francisco Aguilar.

In addition, the team Pacquiao has filled a pre-fight medical questionnaire on Friday, however "a query about any should injury was marked clearly 'No' before" the said form was signed by Pacquiao and his advisor.

"It's something we're looking at, and an issue we'll be discussing with the attorney general," Aguilar added. "Boxers are tough, and it's our job often to protect them from themselves."
