LAS VEGAS, United States - All eyes will be on the judges when Filipino southpaw Manny Pacquiao and Mexico's Juan Manuel Marquez clash in a non-title welterweight bout Saturday (Sunday, December 9, Manila time) at the MGM Grand Hotel.

Organizers took the uprecedented step Friday of having the 3 judges attend the pre-fight rules meeting with both camps in attendance.

The Nevada Athletic Commission invited to the meeting referee Kenny Bayless and the 3 judges -- Adalaide Byrd, Steve Weisfeld and John Keane.

When Pacquiao and Marquez enter the ring Saturday it will be the fourth time in 8 years they have fought.

Pacquiao, who is eager to redeem himself after suffering a defeat in his most recent fight to Tim Bradley, is tired of Marquez blaming his failure to win in their 3 previous fights on biased judging.

Marquez claims he won all three fights -- although two were scored in favor of Pacquiao and one ended in a draw.

Pacquiao's trainer, Freddie Roach told the Las Vegas Review-Journal that he believes the judges will be fair.

"If they do their job like they are supposed to do, everything will be fine," Roach said. - Agence France-Presse
