Choo Sung-hoon Steps Away from TV to Prepare for His Final MMA Fight in November

Choo Sung-hoon is stepping back from variety shows and YouTube content to train full-time for what he has designated his final professional MMA fight. The decision marks a deliberate return to his fighter identity after several years in which he had become at least as recognizable on Korean television as he was in the ring.

The bout is set for November 21 at Gocheok Sky Dome in Seoul's Guro district, as part of Black Combat 17. Choo's camp has confirmed this will be his official retirement fight, closing out a career that ran through K-1, the UFC, and ONE Championship after he transitioned from judo to mixed martial arts.

The broadcast pause covers new variety and entertainment commitments going forward. Programs already filmed before he entered this training block will still air on schedule. Among them is 'Sangnamja's Way of Travel' (상남자의 여행법), a travel show set for October on SBS Plus and MBN, where Choo is paired again with Kim Jong-kook, his co-star from a previous Kyushu edition of the same series.

Also releasing as planned is 'The Boss Went Crazy' (사장님이 미쳤어요), a business-format YouTube series that went live on the 19th. In it, Choo and co-host Lee Eun-ji visit companies with strong products but limited public recognition, spending a day inside the business to assess management and propose marketing strategy. The first episode features Mongcloss, an eco-friendly household beauty brand. The production team noted in a statement that, given this is Choo's final stretch as a fighter, they are rooting for him more sincerely than they might for most guests.

Choo built his media presence gradually, appearing across a range of Korean variety formats in a role that leaned on his dry humor and the novelty of a veteran combat athlete in domestic settings. That familiarity with general audiences makes the pause more noticeable than it might be for a fighter who had stayed closer to the sport full-time.

What shape his final performance takes at Gocheok Sky Dome in November is the question his team, and likely a significant number of viewers, will now be waiting to answer.
