LAS VEGAS -- Oscar De La Hoya and Shane Mosley have the date. All that's left is a site for their June 17 fight.

Promoter Bob Arum flew to Los Angeles on Monday to try and complete negotiations for a fight that would match the two hometown welterweights at the Staples Center.

If officials at Staples come up with $6 million or so and agree to other terms, Arum said the fight will be theirs.

"We're going to go with them if all terms are comparable," Arum said. "Right now, Staples has the best deal on the table."

Arum is also negotiating with the Mandalay Bay hotel-casino for the fight, and said another unnamed Las Vegas resort may also enter the bidding.

The Staples deal, though, intrigues Arum because it would be the first boxing card at the new arena and would match two fighters who both grew up and live in the Los Angeles area.

"There's a lot of drama in opening the arena for boxing with two LA fighters," Arum said.

In addition, if the Los Angeles Lakers make the NBA Finals, the fight could be sandwiched between Game 6 and Game 7 of the championship series.

Arum said last week that De La Hoya and Mosley had agreed in principle to terms for the fight, which would pay De La Hoya some $7 million and Mosley about $4 million.

Arum said Mosley's lawyer looked over the contract Monday and sent it to his promoter, Cedric Kushner, for final approval.

Arum had wavered on the date for the fight, choosing June 10 if it was in Las Vegas and June 17 if it was in Los Angeles. But, with rival promoter Don King now asking for a June 3 fight date for a heavyweight bout between Evander Holyfield and John Ruiz at Caesars Palace, Arum said the bout will be June 17 no matter where it is held.

"It seems silly to put on two major boxing shows within a week of each other," he said.

In Mosley, De La Hoya will be facing a former IBF lightweight champion with a 34-0 record (32 knockouts) who has won twice since moving up to welterweight.

Assuming Felix Trinidad gives up his WBC and IBF welterweight titles after beating David Reid for the WBA super welterweight title on Friday, the De La Hoya-Mosley fight could be a match for the WBC title.

De La Hoya would be recognized as WBC champion on the strength of his seventh-round technical knockout of Derrell Coley in their elimination bout last month in Madison Square Garden in New York.
