Jonathan "Geo Don" Lopez will enter the paid ranks for the first time when he makes his professional debut on Thursday. Lopez goes up against Edwin Salcido (3-3, 2 KOs) at the Marinaterra Hotel Spa in San Carlos, Sonora, Mexico, on an event promoted by Roy Jones Jr. A Floridian of Puerto Rican descent, Lopez had a successful amateur career, winning gold medals at a number of major national tournaments in the USA, and now at only 17 years of age wants to become one the youngest ever boxers to win a world title. Up first for Lopez is Salcido, loser of three straight, allthough in two of those bouts, he was matched against undefeated opponents.
