Boxing-Pacquiao set for Dec. 8 bout with Marquez - reports

LOS ANGELES, Sept 13 (Reuters) - Filipino southpaw Manny

Pacquiao is expected to return to the ring on Dec. 8 for a

fourth fight against long-time rival Juan Manuel Marquez of

Mexico, according to several media reports.

Promoter Bob Arum told Reuters on Thursday that fight

negotiations were being hammered out this week with a decision

likely in "a couple of days."

Arum was not prepared to give any further details, though

some media have reported that a formal news conference promoting

the fight will take place on Tuesday in Los Angeles.

Pacquiao beat Marquez with a controversial majority decision

when they met in Las Vegas in November, and said afterwards he

would be happy to take on the Mexican again "any time."

The Filipino has fought just once since then, surrendering

his WBO welterweight title on a hotly disputed split decision to

American Timothy Bradley in Las Vegas in June.

That stunning result ended a run of 15 consecutive wins by

Pacquiao, who has won world titles in an unprecedented eight

weight divisions.

After that fight, both boxers expressed enthusiasm for a

re-match on Nov. 10.

"It will make me a warrior in having this kind of re-match,"

Pacquiao, whose record slipped to 54-4-2 with 38 knockouts, said

at the time. "In the re-match, I want to finish him before the

whole 12 rounds. I want the re-match."

However that re-match has since been put on ice, reportedly

because the pay-per-view sales for their first bout were

relatively weak.

Bradley was a 5-1 underdog against Pacquiao and their June 7

fight failed to attract a sellout crowd at the MGM Grand Garden

Arena.

TOUGHEST OPPONENT

In contrast, Marquez has consistently been the Filipino's

toughest opponent and their most recent bout generated nearly

400,000 more pay-per-view buys than the Bradley-Pacquiao fight.

Marquez and Pacquiao are renowned for their aggressive

approach in the ring and they fought to a draw when they first

met in May 2004.

The Mexican then lost his WBC super-featherweight title to

the Filipino in a controversial one-point split decision in

March 2008.

Ten months ago, Pacquiao was tested to the full in their

third encounter before narrowly retaining his WBO welterweight

title after his preparations had been hampered by various

distractions, including marital difficulties.

Though the southpaw earned two of the verdicts from the

three judges, he delivered one of the least impressive

performances of his career and boos echoed around the arena from

the disgruntled Mexican fans.

Asked afterwards if he would consider a fourth bout with

three-division world champion Marquez, Pacquiao replied: "Any

time, any time. I am a fighter and my job is to fight in the

ring."

Marquez, who lifted his arms in triumph when that fight

ended, was bitterly disappointed with the outcome, after firmly

believing he had been cheated of victory in his two previous

meetings with Pacquiao.

"It's hard when you're fighting your rival and the three

judges, too," the Mexican said in his dressing room, having

stormed out of the ring after the decision was announced and his

chance of vindication denied. "I got robbed."
