The lightweight champion of the World Boxing Council (WBC), American Devin Haney (24-0, 15 knockouts) must defend his crown against the Dominican Javier Fortuna (35-2-1, 24 knockouts).
If an agreement between the two parties is not reached, a purse bid will be held in Mexico City on December 13.
Haney made his first defense last Saturday night at the Staples Center in Los Angeles, when he dominated the undefeated Alfredo Santiago in twelve rounds.
Fortuna is a former world champion who has won six of his last seven fights. He became the mandatory WBC challenger on November 2, when he defeated Jesús Cuéllar in two rounds by knockout.
