Oswlado Küchle, promoter of Marco Antonio "Veneno" Rubio (58-6-1, 50KOs), is starting immediate negotiations with Salvatore Cherchi, promoter Domenico Spada (38-4, 19KOs), for a March date with the vacant WBC interim-middleweight championship at stake. Full WBC middleweight champion Sergio Martinez will be ordered to fight the winner. Kuchle wants to make the fight at the Estadio TSM, home of the Santos Laguna. The venue is located in Torreón, Coahuila, Mexico and holds 30,000 fans. Martinez is likely going to defend his title on June 7th against Miguel Cotto.
