Pacquiao vs Marquez Undercard: Live Results and Round-By-Round Coverage

Tonight at 9 p.m. EST from the MGM Grand in Las Vegas, live on HBO pay-per-view (U.S.), Top Rank streaming pay-per-view, and Primetime pay-per-view (U.K.), the Pacquiao vs Marquez III card will go live. Three fights precede the main event, and we'll have live updates in the comments of this post, plus immediate post-fight analysis of each bout as they happen on the front page.

The featured undercard attraction will see WBO junior welterweight titlist Timothy Bradley (27-0, 11 KO) face badly faded 40-year-old Joel Casamayor (38-5-1, 22 KO). The fight has been widely criticized by those who feel it's a lousy matchup, and you'd be right and fair to wonder how Casamayor has been deemed a worthy title challenger by the WBO in 2011, but the real purpose of this fight is for Top Rank to showcase Bradley on a major card, as he could be a possible Pacquiao opponent in 2012.

Another junior welterweight matchup is on the card, as Mike Alvarado (31-0, 22 KO) will be facing the only man to ever defeat Amir Khan in the pro ranks, Colombia's Breidis Prescott (24-3, 19 KO). While Prescott has been exposed since the Khan fight, he fought well in his last outing, a questionable decision in Belfast on September 10, losing to Paul McCloskey. Top Rank is back to giving Alvarado, 31, a slight push, no doubt hoping that his outside-the-ring troubles are behind him.

The show's opener will be a super featherweight 10-round attraction pitting Puerto Rico's Luis Cruz (19-0, 15 KO) against Mexico's Juan Carlos Burgos (27-1, 19 KO). This may be the best, most evenly matched fight on the card when all is said and done.
