Kim had long been the most notable figure in Korean boxing, and is the last Korean fighter to have won an OPBF title, with his success having brougth him to the West in recent years, with several wins in North America. It seemed that he was moving on to bigger and better things in the US but unfortunately the injury woes curtailed those dreams of moving onto a world title bout.
Kim began his professional career back in 2010, suffering a 5th round TKO loss to the experienced and tough Taek Min Kim. That loss was quickly put behind him and just 2 years later he claimed the OPBF title, stopping Romeo Jakosalem. He would defend that title 4 times, scoring notable wins over Pan Soo Kim, Shinya Iwabuchi and Valentine Hosokawa, before relocating and basing himself Mexico, resurfacing after 19 months out of the ring.
In North America he became part of team around Leo Santa Cruz and went on to some minor success winning 5 bouts in the west, 4 by stoppage, with the latest of those being a destructive win over Louis Cruz back in July. Sadly though it seems that that will be his final career bout and sources have reported that he is retiring and has no intention of returning to the ring.
The loss is a huge one for Korean boxing with the country losing it's most notable fighter, though if it allows Kim to have a better quality of life going forward we can't criticise him too much and we hope him all the best in life, hopefully with his sight being saved.
