It’s official… There will be a third encounter between the two most ferocious boxing athletes in the world: Manny “Pacman” Pacquiao and Juan Manuel “Dinamita” Marquez.

Top Rank promoter Bob Arum told ESPN.com that he made a deal with Marquez on Tuesday in Los Angeles for the lightweight champion to move up in weight to challenge Pacquiao for his welterweight title on Nov. 12

Pacquiao regularly weighs below 147 for his fights, and Marquez would be moving up from the 135-pound division. In 2009, in his only other welterweight fight, Marquez lost a lopsided decision to Floyd Mayweather Jr., who most would like to see Pacquiao face. Most believe it would be the biggest money fight in boxing history, but Mayweather has repeatedly declined the fight.

With the Pacquiao fight on the line, Arum said Marquez plans to take a tune-up against faded former lightweight titlist David Diaz (36-3-1, 17 KOs) on July 2 in Mexico City. Diaz lost his title to Pacquiao via a lopsided ninth-round knockout in 2008.



Arum said the fight almost assuredly will be at the MGM Grand, even though there are overseas venues interested in making offers.
"I've been spending my life with these offers from Singapore, Macau, Dubai," Arum said. "As far as I am concerned the only offer to cash in on are the ones from the MGM and Cowboys Stadium [where Pacquiao fought twice in 2010]."
Arum said the MGM Grand originally told him the Grand Garden Arena was only available on Nov. 5 because there were Eagles concerts booked there on Nov. 12 and Nov. 19.
"I told them, 'You knew we wanted Nov. 12,' " Arum said. "They said, no I didn't, whatever, we went back and forth. Anyway, I am good friends with the manager of the Eagles, Irving Azoff. I've know him for years. So I called him up and told him the issue and he called the band. An hour later, he called back and said no problem.
"He said the band wanted to send us a message -- 'Because we so admire Manny Pacquiao, we would be privileged to move our concert to Nov. 5.' We're going to invite the Eagles to the fight."
