Mañana en el Estadio Luna Park de Buenos Aires. Diez asaltos de boxeo programadas en la división de peso mediano. (Tomorrow at Luna Park Stadium in Buenos Aires. Ten rounds of fighting scheduled in the middleweight division.) This marks the sixth leg of SGM's comeback tour, after the former WBC middleweight champion of the world retired in 2015 with a knee injury. He returned in 2020 and has gone 5-0 since, but against middling opposition (the best being Britain's basic Brummie battler, Brian Rose). He is still world ranked and on a crusade - a quixotic one, putting it politely - to regain a title belt despite now pushing 50. Teherán is himself no spring chicken at 38 years old, but has an entire decade of youth on the man once known as "Sexy Sergio", who turned 48 last month. Teherán hails from Colombia, boasting what has come to be the country's stereotypical "glass cannon" record, with most of his victories (all domestic) and both of his defeats coming via KO.
