The 35-year-old Pacquiao (55-5-2, 38 KOs), who has won world titles in a record eight weight classes and is also a congressman in the Philippines, has also fought twice and is a much different fighter now than he was then, getting knocked out cold by Marquez in the sixth round in December 2012 and returning to score a lopsided decision win in a tentative performance against Brandon Rios in November in Macau, China.
Bradley (31-0, 12 KOs), 30, of Palm Springs, Calif., got the fight over second-choice Provodnikov, who, after losing to Bradley, went on to win a junior welterweight world title from Mike Alvarado in October.
"Bradley really established himself and differentiated himself from the pack with the Provodnikov and Marquez wins and he really wanted this rematch. So did Manny," duBoef said. "They both wanted the fight. Manny wants to set the record straight about the first fight and Timmy wants to erase the thought that he was given a gift. He thinks he won legitimately the first time and he says he will do it again."
Arum said both fighters agreed to random blood and urine drug testing leading up to the fight to be conducted by the Voluntary Anti-Doping Association, which is headed by Dr. Margaret Goodman, the former chief ringside doctor for the Nevada State Athletic Commission. Arum said Goodman would work closely with the commission every step of the way with regard to the testing.
Arum said when it comes time for the Nevada commission to select the judges and referee -- a point of significant interest for the fight, considering what happened the first time around -- he will ask that the panel consider officials besides just those who work in Nevada, which is how it has operated for years. However, commission executive director Keith Kizer, who championed that policy, stepped down this month.
"This fight will be regulated by a new executive director, whoever that may be, and I am going to ask that the commission cast as wide a net as possible for potential officials," Arum said. "I don't think they should be limited to just Nevada officials. Not the same old, same old. Hopefully, the commission will go along with that."
DuBoef negotiated the deal with Bradley and his wife, Monica, because Bradley's contract with longtime manager Cameron Dunkin expired and Bradley did not renew. Part of the talks for the fight included extending his Top Rank promotional deal. That means Bradley is off the table as a possible opponent for pound-for-pound for king and fellow welterweight titleholder Floyd Mayweather Jr. next year because he's with rivals Showtime and Golden Boy Promotions.
"We had conversations from the beginning about going forward to extend him beyond our current obligations," duBoef said. "The promotional deal was not an add-on. It was always part of the conversation. Now Timmy has a big, lucrative package deal that includes the Pacquiao fight and beyond. Monica and I have been dealing with it for a few weeks. I listened to their needs and they listened to mine and a fair deal was made by everybody."
Pacquiao's deal with Top Rank is due to expire at the end of the year, but Arum said the deal for the Bradley rematch does not include an extension.
"We are engaged in discussions on an extension, but we're not there yet," Arum said.
