Nevada State Athletic Commission Executive Director Keith Kizer told the Los Angeles Times' Lance Pugmire that no such action would be needed, saying, "Every fighter who loses a close fight looks at the judges."
He also conceded however, "I think every judge should strive to get better."
Kizer's comments came on the heels of criticisms from Arum and White after the controversial result kept Bradley's undefeated streak alive, while causing Pacquiao to drop his title.
Arum told Yahoo Sports' Kevin Iole that he wanted an investigation to see if someone rigged the outcome of the bout.
"I want to investigate whether there was any undue influence, whether the [Nevada Athletic Commission] gave any particular instruction and how they came to this conclusion," said Arum.
"If this was a subjective view that each of [the judges] honestly held, OK. I would still disagree, but then we're off the hook in terms of there being no conspiracy. But there needs to be an independent investigation because it strains credulity that an event everybody saw as one-sided on way all three judges saw it as close. It strains credulity."
Arum also said he would hold off on a Pacquiao-Bradley rematch until Nevada attorney general Catherine Cortez Masto agreed to such a probe.
UFC President Dana White was also unafraid to share his opinion regarding the match, tweeting out to his followers, "Nevada state athletic commission at its finest!!! You've for to be f***ing kidding me!! that is disgusting Nevada state athletic commission!!" and "Worst athletic commission in the country!!!!!!!"
Earlier today, judges Duane Ford and Jerry Roth defended their scores in an interview with Steve Carp of the Las Vegas Review-Journal.
Ford said that he thought "Bradley gave Pacquiao a boxing lesson," and thus scored it 115-113 for Bradley.
Roth, who gave the match to Pacquiao, 115-113, said, "[Despite the last three rounds] I still thought Pacquiao had done enough to win."
The third judge, CJ Ross, declined to comment. She scored it 115-113 for Bradley.
Nevada State Athletic Commission chairman Skip Avansino reiterated what co-worker Keith Kizer said when asked if the judges acted inappropriately, saying, "We had three seasoned professionals working and I don't question their determinations.
"I'm not going to second-guess our judges."
Curiously, Arum was hit with a $125,000 fine by the Nevada State Athletic Commission back in 1995, due to an attempt to bribe the International Boxing Federation. At the time, it was the highest fine ever issued, Sports Illustrated wrote. - AMD, GMA News
