LAS VEGAS — Promoter Bob Arum flew Wednesday to the Philippines with a proposed contract for a March 13 fight between Manny Pacquiao and Floyd Mayweather Jr.

The contract was agreed to by Mayweather’s representatives, but the boxer has yet to sign. Arum was to present the proposal to Pacquiao, but there are no guarantees he will agree.
Still, the fact Arum would make the trip to the Philippines to try and get his fighter to sign for the bout was an indication that the megafight was moving forward. It would match the two fighters regarded as the best pound-for-pound in the world in a bout at 147 pounds.
The fight was originally projected for May, but Pacquiao’s candidacy for Congress in the Philippines forced promoters to move it forward to March. The Philippine national elections are in May, and Pacquiao wanted to be at home to campaign.
Promoters for both fighters had agreed to a blackout on negotiations for the bout, so no one would comment on the record. A person close to the promotion spoke on terms his identity would remain confidential.
If the fight is made, there would likely be a Jan. 11 press conference in New York to announce it. The bout could be the richest ever, assuming pay-per-view projections are accurate.
Representatives of the Superdome in New Orleans and the new Dallas Cowboys’ stadium have expressed interest in hosting the fight, as has the MGM Grand hotel-casino in Las Vegas, where the fighters have fought their biggest fights. There is also a proposal for a 30,000-seat temporary stadium on the Las Vegas Strip across from the Wynn resort.
Oddsmakers are already taking bets on the fight, with most making the undefeated Mayweather a slight favorite.
