Whistle and Screen: Vietnam's Ring Officials Are Learning to Trust VAR

The whistle didn't blow. That is the worst moment.

In the middle of a ring at a small arena in District 7, Saigon, two Muay Thai fighters stood facing each other after three rounds, neither believing they had lost. The stands began to roar. The red corner gestured toward the judging panel. The blue corner bowed his head, wiped sweat with a towel, waiting for a verdict from above. I stood at my familiar position — close to the mat, behind the judges' row, where a referee is permitted to observe. Not from the stands. Not from the big screen. Just the floor, the sweat, and the breathing of two people who had just done something very few in Vietnam get to do: step into a professional ring and trade their bodies for a single moment called victory.

Three judges. Three scorecards. Two cards at 29-28. One card at 29-28 the other way. No unanimity. No replay screen. No one sitting before a monitor to say: hold on, that elbow in the second minute of round three, did it really land on the face or just graze it?

I have lived with nights like that for years. And I have begun to think that the biggest story of Vietnamese martial arts in this decade is not who becomes champion. It is whether we have the courage to look at ourselves through a screen.

Context: a martial arts scene growing faster than its scoring system

Muay Thai, kickboxing, and combat sports in Vietnam have taken a significant step forward over the past ten years. The number of gyms has grown, the number of national and regional tournaments has grown, and the number of Vietnamese athletes competing on international stages has grown. But the referee and judging structure has barely moved. Most domestic fights still rely on three judges seated at ringside, each viewing from a different angle, scoring by feel and experience. That is not laziness. It is how the sport has operated since it arrived in Vietnam, and it has produced an entire generation of excellent referees using only the naked eye.

The problem lies elsewhere. The sport has shifted from amateur playground to semi-professional arena, where there is prize money, sponsorship contracts, and commercial image for fighters. When money appears, the margin of error of the naked eye begins to carry a price. A wrong score is no longer just one person's sadness. It is money unpaid, an opportunity unopened, a rung on the ladder never climbed.

Around the world, major organizations are far ahead. ONE Championship uses video review for disputed sequences. Professional boxing has state athletic commissions and official review procedures. Even in Southeast Asian kickboxing circuits, video replay has existed for years. Vietnam does not lack equipment. Television stations film bouts from four to six angles. Spectators' phones film too. The problem is not that we lack footage. The problem is that we lack a process to turn that footage into part of the verdict.

What the screen does not see: three cameras, three different truths

When people talk about VAR in football, they imagine a fairness machine. But when you stand in a ring and rewatch the footage, you understand that the screen has its own perspective too. And every perspective has a blind spot.

Take a specific sequence. A fighter throws a roundhouse kick to the head. The main camera sits at ring height, offset forty-five degrees, and captures the moment of foot-to-target contact. It looks powerful. Very clear. Television viewers will shout: it landed! But the second camera, placed at a low angle near the mat, shows the kick mostly grazing through, its force absorbed by a guarding glove. And the third camera, behind the back of the fighter being hit, shows his head only tilting slightly, with no sign of being stunned.

Three cameras. Three stories. One event.

This is the point few spectators understand: in combat sports, unlike football, contact is not the only criterion. A strike that "lands" in an image may not "score" under the rules. Muay Thai and kickboxing rules require evaluating degree of impact, posture after contact, and control of the situation. A kick that lands but does not unbalance the opponent may score less than a kick that misses but forces the opponent to retreat and lose rhythm.

Over years of watching bouts in Vietnam, I have recognised a paradox: ringside judges are often more accurate than camera lenses in pivotal situations. Because they feel the sound of impact. They hear the exhale of the fighter who is hit. They see whose body is advancing and whose is retreating. That is something the screen cannot capture, no matter how many frames per second.

The blind spot is that we fail to see we need both

So is VAR necessary? My answer is yes, but not in the way most people imagine.

If we apply VAR after the football model in Vietnamese combat sports — a video referee in a separate room with authority to overturn decisions on the spot — we will create a new bureaucratic layer without solving anything. Because the core question in martial arts is not "landed or not." The question is "how to score what landed." And that still requires a human being.

What Vietnamese martial arts needs, I believe, is not an all-powerful VAR, but a post-fight review system. A three-person panel with authority, reviewing the entire bout within seventy-two hours of the final bell. They have the power to confirm, adjust, or record serious errors. Not to change results on the spot — because that would break the rhythm of competition and the emotion of the crowd — but on-the-spot handling is not enough. There must be a second look.

This is the logic behind every review system in the world. Not to fix every score. But to create a shared standard, so that referees can sit down together and talk about what they saw. Consistency does not come from a screen. It comes from dialogue between people, supported by evidence.

The truth is the community needs to trust people, and people need to be supported by data

Over the past few years, I have witnessed a worrying phenomenon. After every major tournament, social media is flooded with clips cut from television, each person cutting a verdict of their own. Fans at home crown themselves referees. And the actual referees — those who stood under the lights, felt the heat of the fight — are criticised by people who have never stepped into a ring.

This creates a dangerous cycle. Referees fear error. Referees err more when they fear. Fans doubt more when referees err. In the end, the trust of an entire community shatters into thousands of pieces, and none of us know where to begin reassembling it.

I have been in that position. I have been scolded by hundreds for holding a view contrary to the majority on a single play. I have had to choose between the truth I saw and the comfort the community wanted to hear. The night I let my hands tremble and edited a conclusion under pressure — that is a memory I do not wish to repeat, nor wish on the next generation of referees.

And I have come to understand one thing: the community does not need a perfect referee. The community needs an honest one. Someone willing to say "I may be wrong," and willing to sit down and review what they did.

The contrarian point: data can harm martial arts

Here is what few dare to say: if we equip VAR for every small tournament in Vietnam without accompanying training, we will produce a generation of dependent referees. They will no longer trust their own eyes. They will wait for the screen. They will fear making decisions. And the art of refereeing — which I believe is one of the hardest skills in sport — will wither.

I have lived and worked with referees who can sense a fight from the breathing of the fighters alone. That is intuition forged over thousands of hours standing under a ring. If we place a screen above that intuition, we trade an invaluable asset for a limited tool.

The right tool is not one that replaces the human being. The right tool is one that helps the human being trust themselves more.

And that is why I believe the first step in Vietnam is not buying a VAR system. It is training. It is building a shared code. It is teaching referees to look back on themselves without fear. It is teaching fans to argue without attacking. Only then does a screen placed beside a ring truly mean something.

Toward a mature martial arts scene

People often assume technology makes sport fairer. I am not certain. Technology makes sport more transparent. Fairness must still come from people — from a referee who understands that their verdict does not merely hand over a belt, but hands over trust.

On that night in District 7, when the three cards were read and the red corner slumped in disappointment, I stayed twenty more minutes after the arena emptied. I asked myself: with a screen, would the result have been different? Perhaps. But a different result is not the most important thing. The important thing is that the fighter walks away without having to wonder whether he was treated unfairly.

Vietnamese martial arts is at a fork. One path is the old road, where the referee is the only person who knows the truth, and fans can only believe or not believe. The other is a new road, where everyone looks at the same screen and argues together. I do not know which path we will choose. But I know that somewhere out there, a young fighter is preparing to step into a ring for the first time, and they deserve to know that the whistle blew for a just reason.
