Manny Pacquiao vs. Timothy Bradley get it on from the MGM Grand Hotel and Casino in Las Vegas, Nevada Saturday night after the conclusion of the Heat vs. Celtics game.

Bob Arum, Pacquiao's promoter, says that the fight won't go on until the Celtics' game ends as his fighter is a fan.

The two boxers are fighting for the WBO Welterweight title, currently held by Pacquiao since the fall of 2009. Bradley is making the jump from the Light Welterweight class. He retained his title when he beat Joel Casamayor on Nov. 12, 2011.

Bradley is undefeated in his career, going 28-0 with 12 knockouts. Despite his undefeated record he is a huge underdog. Much of the public views him as just another part of the holding pattern while Pacquiao and Floyd Mayweather continue to dance around each other.

Pacquiao will earn $26 million for the fight. Bradley will take in at least $5 million. Both can earn more, depending on the Pay Per View sales figures.

The fight coverage starts on Pay-Per-View at 9 p.m. ET and costs $54.99. The main event between Pac-Man and Bradley won't begin until the Celtics-Heat game concludes, likely just after 11 p.m. ET.

Here is the fight card for Saturday night at the MGM Grand Garden Arena in Las Vegas, Nevada:

Welterweight: Manny Pacquiao (champion) vs. Timothy Bradley

Welterweight: Mike Jones vs. Randall Bailey

Super Bantamweight: Guillermo Rigondeaux (champion) vs. Teon Kennedy

Junior middleweight: Jorge Arce (champion) vs. Jesus Rojas

Prediction: Pacquiao is a machine who has laid low fighters for years. It will happen again here. But it will not be without its entertainment. Bradley is an excellent fighter as well and he will undoubtedly give Pacquiao more than he has gotten from most of his recent fights. Pacquiao in a split decision.
