Former UFC featherweight “Sting” Seung Woo Choi is back in training after more than a year away from competition, signaling a potential return to the cage with a renewed mindset.
Former UFC featherweight Seung Woo Choi appears to be preparing for a return to mixed martial arts after stepping away from competition following his departure from the UFC in March 2025.
The South Korean fighter, widely known by his nickname “Sting,” recently appeared in a video on coach Dong Ho Ha’s YouTube channel, where he openly discussed his motivation for returning to training and reflected on the mental challenges that accompanied the final stages of his UFC career.
When asked why he had resumed training seriously, Choi offered a straightforward response.
“To compete in a fight.”
The comment marks one of the clearest indications yet that the 33-year-old is considering a return to professional MMA, although no opponent or official fight date has been announced.
Choi Returns to Training After 19 Months Away
During the YouTube appearance, Choi participated in mitt training with coach Dong Ho Ha, working through striking combinations as he began rebuilding his rhythm.
Following the session, Choi acknowledged the challenges of returning after an extended period away from the sport.
“It’s been a year and seven months… I think I need to get my feel back.”
The remark reflected the reality of returning to high-level training after nearly 19 months without professional competition.
Choi last competed on March 15, 2025, at UFC Fight Night 254, where he suffered a first-round knockout loss to Argentine prospect Kevin Vallejos.
The defeat marked the end of his UFC tenure, closing a chapter that began when he joined the promotion in 2019.
Following his departure, Choi stepped away from MMA and spent time living outside the demanding routines of professional fighting.
Now, his return to structured training suggests that the former UFC featherweight is beginning to rediscover his competitive motivation.
Reflecting on the Pressure of His Final UFC Fights
Perhaps the most revealing part of Choi’s recent appearance was his reflection on the mental pressure he experienced during the final stages of his UFC career.
Looking back on his last two defeats, Choi described a period when the constant demands of competition left him struggling to find balance.
“I think I lived every single day constantly thinking about things intensely. Maybe I didn’t have any room to breathe.”
The comments offered insight into the emotional challenges that can accompany competing at MMA’s highest level.
During his UFC run, Choi experienced both promising victories and difficult setbacks while facing increasingly competitive opposition.
Known for his aggressive striking style and willingness to engage in exchanges, Choi built a reputation as an entertaining featherweight capable of producing exciting contests.
However, his final stretch inside the Octagon proved difficult.
A knockout loss to Steve Garcia in July 2024 was followed by another first-round stoppage against Vallejos in March 2025, ending his UFC career on consecutive defeats.
Those results appeared to weigh heavily on Choi, who suggested that his previous approach to competition had become mentally exhausting.
A Different Mindset for a Potential Comeback
Despite the challenges of his previous UFC run, Choi appears to be approaching his potential comeback with a noticeably different attitude.
Reflecting on the possibility of fighting again, he smiled and expressed optimism about returning to competition.
“I think I’ll be able to enjoy it this time.”
The statement suggests a shift in perspective for a fighter who previously described living under constant competitive pressure.
Rather than focusing exclusively on results and the expectations associated with competing in the UFC, Choi appears interested in rediscovering the enjoyment that initially drew him to martial arts.
That change in mindset could become an important part of his next chapter.
For fighters returning after extended layoffs, rebuilding confidence and finding the motivation to compete can be just as important as restoring physical conditioning.
Choi’s recent training session indicates that he has begun taking those first steps.
Could ZFN 05 Host Choi’s Return?
Although Choi has not announced an opponent or confirmed his next fight, speculation has emerged surrounding a possible appearance at ZFN 05 on December 19, 2026.
The South Korean promotion has continued developing its presence in the domestic MMA scene, providing opportunities for both established veterans and emerging prospects.
A fighter with Choi’s UFC experience would represent a recognizable addition to the event.
However, there has been no official confirmation that Choi will compete at ZFN 05, and his recent comments did not identify a specific promotion or opponent.
With less than two months remaining before the event, an announcement would be needed to establish whether the potential matchup will materialize.
For now, the possibility remains speculative.
A New Chapter for Sting
Choi’s potential return comes at an interesting stage of his professional career.
Having competed against international opposition throughout his UFC tenure, he brings valuable experience that could make him a significant presence in South Korea’s domestic featherweight division.
His aggressive striking, established name recognition, and experience competing on the sport’s biggest stage could also make him an attractive opponent for younger fighters seeking to establish themselves.
But beyond potential matchups and promotional opportunities, Choi’s recent comments suggest that his return may be driven by something more personal.
After spending years navigating the pressure of professional competition, he now appears interested in approaching the sport with greater freedom and enjoyment.
Whether that leads to a December appearance at ZFN 05 or a later return remains uncertain.
What is clear is that “Sting” Seung Woo Choi is back in the gym, rebuilding his rhythm, and preparing for the possibility of stepping inside the cage once again.
