Former UFC star Dong Hyun Kim shared footage of a sparring session with Conor McGregor at SBG Ireland, creating one of the most talked-about MMA videos in Korean combat sports this week.
Former UFC welterweight contender Dong Hyun Kim has generated significant buzz throughout the Korean MMA community after releasing rare footage of himself sparring with former two-division UFC champion Conor McGregor during a visit to Ireland.
The video, published on Kim’s official YouTube channel, captures the two UFC veterans exchanging technical rounds at SBG Ireland in Dublin. The footage quickly spread across Korean social media platforms and combat sports forums, with fans eager to see two of the sport’s most recognizable personalities sharing the mats together.
For many viewers, it represented a unique crossover between one of Asia’s most influential MMA figures and one of the most famous fighters in UFC history.
Dong Hyun Kim Visits Conor McGregor at SBG Ireland
The sparring session took place during Dong Hyun Kim’s recent European tour, which included visits to several prominent gyms and meetings with fighters across the continent.
While Kim and McGregor had reportedly met during previous visits, this marks the first publicly released footage showing the pair participating in a live sparring session.
The video highlights both fighters’ experience and technical skill despite being at very different stages of their careers.
McGregor displayed the timing, accuracy, and striking precision that helped make him one of the biggest stars in mixed martial arts history. Kim, meanwhile, demonstrated the toughness, composure, and durability that earned him the nickname “Stun Gun” throughout his UFC career.
One sequence in particular drew significant attention online when McGregor landed a clean body shot that briefly forced Kim to double over before continuing the round.
The moment quickly became one of the most shared clips from the session.
Why the Video Is Generating So Much Attention

Part of the video’s appeal comes from the rarity of seeing two fighters from different UFC eras interact in a training environment.
Dong Hyun Kim established himself as one of the most successful Asian fighters in UFC history during his run in the welterweight division. Over the course of his career, he became a pioneer for Korean MMA and helped pave the way for future generations of fighters from South Korea.
Conor McGregor, meanwhile, transformed into one of the sport’s biggest global superstars, becoming the first fighter in UFC history to simultaneously hold titles in two weight classes.
Although the two never competed in the same division, both played important roles in helping the UFC expand internationally during their respective careers.
Their sparring session offered fans a rare glimpse into what happens when two veteran fighters with vastly different styles and backgrounds share the same gym.
Conor McGregor’s Return Speculation Continues
The timing of the footage has also added to the ongoing discussion surrounding McGregor’s future.
The former UFC champion has increasingly shared training content in recent months, fueling speculation that he remains focused on eventually returning to active competition.
Multiple sparring videos, strength and conditioning updates, and gym sessions have surfaced online, drawing significant attention from fans eager to see whether McGregor will fight again.
The footage with Dong Hyun Kim adds another chapter to that story and provides one of the most extensive recent looks at McGregor’s training environment at SBG Ireland.
Dong Hyun Kim’s Growing Role in MMA Media
Although retired from professional competition, Dong Hyun Kim remains one of the most influential figures in Korean combat sports.
Through StunGun TV, television appearances, commentary work, and international training trips, Kim has successfully transitioned from fighter to media personality while maintaining strong connections throughout the global MMA community.
His recent European tour has included training sessions and content collaborations with notable names such as Paddy Pimblett and former UFC welterweight Gunnar Nelson. However, the sparring session with McGregor has easily become the most high-profile moment of the trip.
The video’s popularity also reflects Kim’s unique position within Korean MMA. Few retired fighters possess the credibility, relationships, and audience reach necessary to create this type of international content.
A Meeting of Two UFC Eras
For longtime MMA fans, the sparring session represents more than just a viral training clip.
It serves as a reminder of the impact both fighters had on the sport during their UFC careers.
Dong Hyun Kim helped establish Korean MMA on the global stage through years of success inside the Octagon. Conor McGregor became one of the biggest stars combat sports has ever produced.
Seeing the two share rounds in Dublin offered fans a rare moment that bridged two different chapters of UFC history.
As the video continues circulating online, it remains one of the most talked-about pieces of MMA content to emerge from Korea this year.
