Before his awaited trip back to the Island of Macau, the Philippine boxer Manny Pacquiao will stay in Las Vegas longer than expected. According to Bob Arum, after the Pacquiao vs. Marquez fight tomorrow night at the MandalayBay Resort and Casino, Pacquiao will return to Las Vegas and the MandalayBayEventsCenter by the end of June for his next fight against the WBC lightweight champion David Diaz. Pacquiao was expected to fight David Diaz at the new Venetian casino in Macau, however, due the importance of this fight, the organizers and promoters decided to change the plans and re locate the fight back to SinCity.

Several months ago, Diaz (33-1, 17 KOs) defeated and retired the famous Erik Morales in defense of his belt. Now, the 31-year old finds himself in the middle of the Manny “Pac Man” Pacquiao plans to conquer every boxing federation title in his category. Diaz will be fighting Ramon Montano as part of the Juan Manuel Marquez vs. Pacquiao under card. If Diaz wins and Pacquiao defeats Marquez, the young Mexican-American is guaranteed a well paid bag against the “The Pac Man”.

“If it happens, it’ll be a dream opportunity, but we both have to win. I think Manny has a tough road ahead of him. I can’t discount a great fighter like Juan Manuel Marquez. He could easily ruin everything.” said Diaz.

Pacquiao won six fights in a row before meeting Marquez, who knows his potential after they clashed in the ring about four years ago. Pacquiao will fight Nate Campbell in his return to Macau; Campbell is a 36 year old boxer who became famous after defeating Joel Casamayor in 2003. Campbell also won his first title by defeating Juan Diaz at Plaza de Toros in Cancun.

"The business that Manny brings in is right up their alley, it's what they want here, and (Mandalay Bay) really wanted to have the fight here at the end of June.'' said Arum.
