According to The Fight Network, a last-minute replacement has been found for the Japanese guard player. To wit:
Jung replaces the American Top Team's Gesias "JZ" Calvancante (14-1-1). A two-time winner of the K-1 HERO'S Lightweight Grand Prix, Calvancante was reportedly recovering from both nose and knee surgeries and had been unable to train for the bout.
Hats off to the Japanese for feeding into the Korean vs. Japanese rivalry with a last second replacement. Another salutation to the Japanese for selecting a Korean fighter that is almost certifiably locked to get abused in Aoki's guard.
