At the negotiating table is the potential showdown between World Boxing Organization super bantamweight champion Jessie Magdaleno and mandatory challenger Cesar 'Corazón' Juarez of Mexico, tentatively scheduled for October 31.

Luis Zápari, promoter of Juarez, reveals that an agreement is in place, but some details are missing, such as the television network and the venue, which is why Juárez is already preparing in Mexico City for his second championship fight.

Juarez has previously challenged for a title against Nonito Donaire in Puerto Rico and that resulted in tough defeat for him - in one of the better fights of the year.

Magdaleno (25-0, 18 KO's), who is managed by Frank Espinoza and promoted by Top Rank, won the WBO super bantamweight title from Donaire in an exciting fight that he fought with a touch of intelligence and boxing ability.

"The fight is almost done, we spoke to the promoter, the fighters have agreed and only the signatures are missing. There are details to solve but it seems that the most important thing is already done," Zápari said to ESPN Deportes. "The fight will take place in the United States, but that's no problem because Cesar will go anywhere to fight for the championship."

Magdaleno's first defense was made in April when he knocked out Adeilson Dos Santos of Brazil at the Stub Hub in Carson, California, in two rounds, and now it is now time for him to satisfy the mandatory fight against the highest ranked challenger as ordered by the WBO.

Juarez, meanwhile, is 20-5 with 15 KOs, and would arrive with a three-win streak after being beaten by Donaire in December 2015 and then by Giovanni Delgado unexpectedly in March 2016.

However, he recovered by knocking out top rated Filipino Albert Pagara.

If a deal is reached, there is a big possibility that the fight will be broadcast on ESPN, thanks to the agreement reached by the legendary promoter Bob Arum and the international sports channel.
