Chan Sung Jung “Korean Zombie” breaks down UFC 331, revisits the fights that shaped his own career, and explains why watching Doo Ho Choi move beyond his shadow would mean more to him than protecting his own legacy.
UFC 331 gave Chan Sung Jung plenty to analyze.
But somewhere along the way, the breakdown stopped being only about fights.
In Part 2 of his UFC 331 discussion, “The Korean Zombie” went through a card filled with fighters who have crossed his path in one way or another — from Renato Moicano and Brian Ortega to Joshua Van, Alexandre Pantoja and, most importantly for Korean fans, Joo Sang Yoo and Doo Ho Choi.
Jung described UFC 331 as a card with almost nothing to skip, pointing to recognizable names throughout both the prelims and main card. He specifically highlighted Yoo and Choi while also discussing names such as Gable Steveson, Marlon Vera, Charles Jourdain and the Arman Tsarukyan–Mauricio Ruffy matchup.
But the most revealing moments came when Jung began talking about his own career — and what he wants to see happen to Korean MMA after him.
UFC 331 Is Personal for the Korean Zombie
There are connections almost everywhere Jung looks on this card.
Moicano and Ortega represent two dramatically different moments from his UFC career. Jung stopped Moicano in just 58 seconds in 2019, while his 2020 meeting with Ortega became one of the most difficult nights of his career.
That history makes their UFC 331 rematch particularly interesting from Jung’s perspective.
He noted that the two first fought in 2017 and now meet again under very different circumstances, with Ortega moving into the lightweight division while Moicano has spent years establishing himself there.
For Jung, though, discussing Moicano inevitably brought him back to one of the defining turning points of his own career.
“I Think I Was Lucky”
Jung’s victory over Moicano came immediately after his unforgettable last-second loss to Yair Rodriguez.
Looking back, Jung explained that the Rodriguez fight ultimately changed the way he approached preparation. He spent the first portion of the Moicano camp in Korea before finishing approximately three weeks with Eddie Cha, an experience that began changing the mentality he carried into the Octagon.
The result was one of the finest performances of his career.
Yet years later, Jung’s assessment of the knockout is surprisingly understated.
He described himself as fortunate that the decisive punch landed, reasoning that had the moment unfolded differently, the entire fight could have developed into something else. To Jung, that uncertainty is simply part of combat sports.
“Every fight has luck involved,” was essentially the point he returned to while discussing how quickly a fight can change.
It was a revealing comment from a fighter whose reputation was built around making those chaotic moments happen.
The Yair Rodriguez Loss — and Why Jung Doesn’t Regret It
The discussion became even more personal when Jung revisited Rodriguez.
Before accepting that fight on short notice, Jung said he had originally expected an opponent around Frankie Edgar’s standing. He recalled agreeing to face Rodriguez after asking UFC matchmaker Sean Shelby for one thing: even if he lost, he wanted his next opponent to remain around that same competitive level.
Of course, everyone knows how the fight ended.
Jung appeared headed toward a decision victory before charging into one final exchange. Rodriguez landed the now-famous upward elbow with one second remaining.
Asked whether he regretted that final rush, Jung’s answer offered perhaps the clearest insight into how he now views his career.
He said he believes that moment helped create the person — and fighter — people remember today.
At the time, the loss was devastating. Looking back, however, Jung sees something unmistakably “Korean Zombie” about continuing to attack even when victory appeared to be secured.
The result went against him.
The moment became part of his identity anyway.
Jung Barely Remembers Fighting Brian Ortega
His memories of the Ortega fight are considerably darker.
Jung revealed that after being hit by Ortega’s spinning elbow in the opening round, he remembers almost nothing until the fifth round.
He recalled thinking as the final round began that it was time to regroup and finish strong — only to seemingly realize moments later that the fight was already over.
Jung also admitted that he has barely watched the fight since.
“I don’t fight southpaws like that,” Jung explained while looking back at his performance, saying that without his normal awareness he repeatedly reacted in ways that were completely unlike him.
Still, preparing for Ortega left Jung with an intimate understanding of his game.
One weapon stood above everything else: the guillotine.
Jung described Ortega’s guillotine as one of those techniques that possesses something uniquely difficult to reproduce — the kind of specialty technique that can be understood technically but feels completely different when applied by the fighter who has mastered it.
That is a major reason Jung believes Moicano should be extremely careful about initiating wrestling in their rematch.
Why Jung Sees Moicano vs. Ortega Differently in 2026
The first meeting took place at featherweight.
This time, Jung believes the circumstances are fundamentally different.
Moicano has been competing at lightweight for years, while Ortega is only now making the move. Jung questioned whether Ortega can still rely on the extraordinary durability that once allowed him to absorb punishment and turn fights around.
He also noted that the version of Ortega seen recently has appeared more measured and slower than the relentlessly aggressive fighter who once charged forward through enormous amounts of damage.
Jung’s expectation is therefore that Moicano may have little reason to expose himself to Ortega’s strongest submission opportunities if he believes he can win the striking exchanges.
There is a personal element, too.
When pressed on the matchup, Jung openly admitted that he wants Moicano to win — before laughing about how fighters connected to his career continue bringing his name back into MMA conversations.
That led into the most interesting part of the entire discussion.
“I Want Doo Ho to Surpass Me”
For years, Jung and Doo Ho Choi represented two of the most prominent faces of Korean MMA in the UFC.
And Jung admitted that when both men were active, there was competition.
Not animosity.
Competition.
He wanted to accomplish more. He wanted to be better.
Retirement has changed that completely.
Jung said he now genuinely wants Choi to surpass what he accomplished.
Because Choi is currently one of the Korean fighters positioned furthest along on the UFC stage, Jung wants to help him push beyond the comparisons that have followed Korean fighters for years.
His goal is almost counterintuitive for someone with such a significant legacy.
Jung wants fans to eventually say: the Korean Zombie era is over.
And rather than being threatened by that idea, he said he would feel proud knowing he played some role in helping create what came afterward.
It’s a striking shift from the mentality of an active fighter.
Jung no longer needs to be the measuring stick.
He wants someone else to move it.
Korean Zombie Breaks Down Joshua Van vs. Alexandre Pantoja
Jung also turned his attention to the UFC 331 headliner between Joshua Van and Alexandre Pantoja.
There is another connection here.
Jung recalled recently meeting Van in Las Vegas, where the young fighter enthusiastically greeted him and explained that he had known of the Korean Zombie for years. Jung joked about the interaction, but acknowledged the connection that an Asian striker like Van could naturally have with his career.
When discussing the actual matchup, however, Jung separated that personal connection from his technical assessment.
His concern for Van centers on grappling.
Jung pointed to positions Van surrendered against Tatsuro Taira and argued that giving similar opportunities to Pantoja could be considerably more dangerous because of the Brazilian’s submission threats.
He also questioned whether the relatively short period since the Taira fight provides enough time to close those grappling gaps. In Jung’s view, that is not an area that can necessarily be transformed in only a few months.
At the same time, the discussion acknowledged an important unknown: Pantoja’s age and recent elbow injury.
That uncertainty is exactly what makes the fight interesting.
From Korean Zombie to the Next Generation
By the end of the video, Jung returned to where the conversation started: UFC 331 as a whole.
He encouraged fans to watch from the opening fight rather than waiting for the main card, describing the lineup as one filled with prospects, established names and matchups worth following from beginning to end.
But there were two names he wanted Korean fans to remember above the rest.
Joo Sang Yoo.
Doo Ho Choi.
Jung closed by saying those are the fighters Korean fans should be most excited about and promised to do everything he can to help make UFC 331 a historic day for South Korean MMA.
That final comment captured what made this particular UFC breakdown different.
Chan Sung Jung spent years carrying Korean MMA’s expectations into the Octagon himself.
Now he’s sitting outside it, breaking down fights, coaching the next generation and openly hoping that one of them eventually makes his own shadow a little smaller.
For the Korean Zombie, that wouldn’t erase his legacy.
It would mean Korean MMA had finally moved forward.
