WBC executive secretary Mauricio Sulaiman sent a letter to the parties of WBC welterweight champion Andre Berto (25-0,19 KOs) and former WBA welterweight champion Luis Collazo (30-4,15 KOs) to begin free negotiations of a rematch on their January 17th bout of earlier this year. This ruling had been decided at the last WBC Convention that was held in Chengdu, China. If no agreement is reached then the WBC will conduct a purse bid offer on July 17th at the WBC offices in Mexico City. Berto narrowly defeated Collazo by decision in their bout. Each fighter has had one fight since then. Berto easily decisioned Juan Urango last month, while Collazo to keep busy stopped journeyman David Gogichaishvili this past weekend.
