UFC: ‘Korean Zombie’ reveals he gained 20 kilograms after losing to Brian Ortega
- Jung Chan-sung says ‘the thought my career has crashed brought me down to rock bottom’ and he ate without control
- The 33-year-old also blacked out after fight from sustained blows to head – ‘I don’t remember anything from the second, third and fourth rounds’

UFC featherweight Jung Chan-sung, better known as “The Korean Zombie”, has talked about his crushing defeat to Brian Ortega and how he lost a grip on himself by gaining 20 kilograms.
In a television talk show aired on Monday on SBS Plus, Jung said the training ahead of the fight last October psychologically pressured him so much he could sleep only one and a half hours for two days before the bout.
In the show hosted by television personality Kang Ho-dong, Jung said the loss by unanimous decision was emotionally traumatic, and he perceived it as the end of his career.
He said he had sought a psychiatrist after he returned to Seoul from Abu Dhabi in the United Arab Emirates, where the event was held on Fight Island.
“The thought that my career has crashed brought me down to rock bottom,” said Jung, adding that he ate without control for a month and put on 20 kilograms.
