Professional Combat Sports and the VAR Gap: Lessons from Adalaide Byrd's 118-110 Scorecard

Professional Combat Sports and the VAR Gap: Lessons from Adalaide Byrd's 118-110 Scorecard

On 16 September 2026, at the T-Mobile Arena in Las Vegas, judge Adalaide Byrd scored the twelve-round bout between Gennady Golovkin and Canelo Alvarez 118-110 in favour of Alvarez. The other two judges scored it 115-113 for Golovkin and 114-114. The result was a split draw, and the roughly twenty thousand people inside the arena reacted in a way anyone who has watched boxing instantly recognises.

What made me stop at that scorecard was not the number. It was that after the fight, nobody could rewind a single frame to answer the simplest question: which rounds did Byrd give Golovkin? She was not required to explain. No internal audio was released. No round-by-round record was published in real time. No system cross-checked the three judgments while the fight was unfolding. And above all, there was no VAR.

A year later, the rematch took place on 15 September 2026 and Canelo won by majority decision, with two scorecards of 115-113 and one of 114-114. The controversy did not disappear. It simply changed shape, because the structure that produces controversy remained intact.

That same year, in Nha Trang, I began the work that would shape how I write about sport: tracking all 182 matches of the 2026 V.League season and building a referee error table round by round. In the first ten rounds I logged 214 errors, 67 of which directly affected the outcome. My analysis of the round-12 match between Hanoi FC and SHB Da Nang, where the referee missed a penalty-box incident, drew 50,000 reads and circulated among V.League coaching staff. The 2026 V.League referee error table is not a starting point; it is a mirror held up to an entire system.

What professional combat sports lack is not a new piece of technology. It is a data infrastructure thick enough for fans to verify a judgment themselves, instead of having to trust the reputation of three people seated at ringside.

Two Rulebooks, One Shared Gap

Professional boxing scores on four criteria codified by the Association of Boxing Commissions and Combative Sports: clean punching, effective aggressiveness, ring generalship and defence. MMA scores under the Unified Rules with a different order of priority: effective striking and grappling first, then aggressiveness, then cage control. Both operate on the 10-point must system: the round winner takes 10, the loser 9, and 8 after a knockdown.

That structure is not wrong. It simply cannot defend itself.

In football, controversy always has a physical anchor. Whether the ball crossed the line is binary. Whether a player is level with the last defender is geometry, measurable to the centimetre by the semi-automated offside technology used at the 2026 World Cup. When VAR debuted at the 2026 World Cup, I analysed all 64 matches, 455 VAR interventions and 20 overturned decisions. The 2026 World Cup gave me a question: if the human eye is not enough, why not trust the machine?

Combat sports have no such anchor. Effective striking is not an event; it is a value judgment. A hook landing on the jaw is an event, measurable on camera. Whether that hook is worth more than three low kicks combined is an opinion, and no algorithm settles an opinion. This is the boundary every technology debate in combat sports runs into.

Three Scorecards, Three Cognitive Models

In an MMA or professional boxing bout, three judges sit at three different positions around the cage or ring, and each literally sees a different fight. The diagonal angle gives a better view of one side while obscuring the other. Three people, three distinct visual datasets, and no mechanism to synchronise them before the scorecards are submitted.

CompuBox has existed since 2026 and became the punch-statistics tool widely used in boxing broadcasts. Two operators press buttons for every landed and thrown strike. It sounds objective, but it is a manual count, not a measurement system. It counts volume, not quality. A jab that grazes a glove and a jab that stuns an opponent are logged the same way. Most importantly, judges are not given live CompuBox data during the fight.

So three judges score from memory and from a feel for the fight's rhythm, while the outside world holds a different dataset. When the two diverge, we get controversy. When controversy erupts, we have nothing with which to adjudicate.

Replay review in MMA is tightly restricted. Most commissions allow the referee to use replay only in narrow situations, typically for a fight-ending sequence or to check whether a stoppage was correctly timed. No commission permits rewinding to examine how a completed round was scored. Every slow-motion replay is a surgery: cut right, cut wrong, but never cut in haste. In professional combat sports, that surgery is not even allowed to begin.

Publishing round-by-round scores in real time has been trialled in a handful of places worldwide and immediately proved contentious, because fighters who know whether they are ahead or behind will change how they approach the next round entirely. This is one of the sport's hardest paradoxes: greater transparency can reduce competitiveness, while keeping scores secret to protect competitiveness erodes trust.

Weight Cutting: Bad Data Before the Fight Begins

There is a data layer fans rarely see but which directly shapes everything that follows: body weight.

A professional MMA or boxing athlete typically steps on the scale 7 to 12 kilograms below their actual fighting weight. After weigh-in they have roughly 24 to 36 hours to rehydrate and refuel. During that window the body undergoes a recovery process that no device fully measures. The scale records a single number at a single moment, and that number says nothing about the athlete's true state when the first bell rings.

The consequences have been measured in lives. On 11 December 2026, in Kuala Lumpur, 21-year-old Chinese fighter Yang Jian Bing died from complications related to his pre-fight weight cut at a major MMA event. His death forced many organisations to change procedure. The California State Athletic Commission adopted a ten-point plan in 2026 to control weight cutting, including urine specific gravity testing to determine dehydration levels. Several major Asian promotions subsequently introduced hydration testing before athletes were allowed to weigh in.

The crucial point is this: most jurisdictions still record the metrics internally only, do not publish them fully, and do not hold enough data to reconstruct an athlete's physiological history over years of competition. A fighter can cut weight excessively twenty times across a career without any public record capturing that sequence.

The Economics of Uncertainty

Professional combat sports monetise uncertainty itself. A fight with a disputed result still sells tickets for the rematch. But confidence in the scoring system is a long-term asset, and that asset depreciates with every strange scorecard.

According to figures reported in the American sports press, the broadcast deal between the UFC and ESPN signed in 2026 was worth approximately 1.5 billion US dollars over five years. That figure shows how much money flows into the industry, and how much pressure sits on the organising body to keep the product attractive.

Further down, fighter compensation is highly centralised. The exclusive apparel deal the UFC signed with Reebok in 2026, later shifting to Venum in 2026, replaced fighters' freedom to negotiate individual sponsorships inside the cage. For lower-earning athletes, personal sponsorship income had been a lifeline. Widely circulated estimates put the share of revenue going to fighters in the UFC well below the roughly 50 per cent common in major American team sports leagues.

Betting markets complicate the picture further. When a fight's outcome depends on the subjective judgment of three people, the betting variable no longer sits on the canvas. It sits in the referee's record, in each judge's scoring style, in the history of scorecards they have produced. That is a category of data that has never been standardised or broadly published, while the money wagered on it was institutionalised long ago.

Governance: The Olympic Border

Governance shows that the data problem cannot be separated from the organisational one.

Boxing has been through a prolonged crisis of confidence. After controversies over officiating and financial management, the International Olympic Committee stripped the international boxing federation of its role in organising Olympic boxing ahead of Tokyo 2026, and ran the boxing competition at Tokyo 2026 and Paris 2026 itself. At its session on 16 October 2026 in Mumbai, the International Olympic Committee approved boxing's inclusion in the Los Angeles 2028 programme.

That is a positive decision for the sport. It also raises a question the professional community has not answered: if the sport's governing body could not retain credibility at the highest level, how is scoring data being controlled at the lowest level?

Where Vietnam Sits on That Map

Vietnam has a deep traditional martial arts culture and a modern combat sports market taking shape. LION Championship, the domestic professional MMA promotion, has produced a generation of fighters competing regularly in front of the public. Vietnamese boxing has made progress on the regional stage, and recent SEA Games editions show the pool of young fighters thickening, along with rising public expectation.

But if I speak plainly, in the way I have always spoken about the V.League: we are running a sport that produces disputes without an infrastructure for recording disputes.

Based on my experience tracking matches and archiving data, a combat sports scene matures only when three things exist simultaneously: public referee records for every event, punch statistics published after each round, and a formal review process when an official complaint is filed. Without those three, every argument about fairness ends exactly where it began: personal belief.

Counterintuitive: VAR Will Not Save Combat Sports

This is where I want to part company with most fans.

After every contentious decision, the reflex is to demand technology. Demand VAR. Demand automated scoring. Demand high-speed cameras from every angle. Demand artificial intelligence analysing every strike. That demand is emotionally right and structurally wrong.

VAR works in football because football has a layer of physical truth a machine can establish better than the human eye. Offside is geometry. A ball over the line is optics. A handball in the box is a contact event. Even when VAR is contentious, it always terminates in a question that has an answer.

Combat sports have no such layer. High-speed cameras can confirm that a strike landed. They cannot confirm whether that strike is worth 10 points or 9. This is a problem of the measuring scale, not of eyesight. Equipping an ambiguous scale with more machinery only manufactures a false sense of precision, and false precision is more dangerous than acknowledged ambiguity.

The bigger blind spot lies in the criteria themselves. Boxing's four criteria can point in opposite directions within the same round. A fighter retreating constantly while countering cleanly may win on clean punching and lose on effective aggressiveness. No official weighting states which criterion outranks which in any given round. Each judge builds a private scale in their head, and that scale shifts with the fight, the opponent and the atmosphere in the arena.

So attributing every strange scorecard to an individual judge is the easiest explanation and the least useful one. I never say a referee is wrong. I only say their angle has not been given enough light.

What Comes Next

Looking ahead, I see three scenarios unfolding over the next five to ten years.

The first: major promotions standardise a transparency infrastructure, publishing round scores as each round ends, disclosing judges' identities and scoring histories, recording internal review-room audio and releasing it when a formal complaint is lodged. Controversy would remain, but it would rest on criteria rather than suspicion.

The second: the industry keeps its current structure. Each disputed scorecard then erodes another layer of trust. Money keeps flowing into the biggest events, but the commercial value of smaller shows is dragged down, because fans no longer believe results reflect ability.

The third: image-assisted and AI scoring enters trials. That opens a new layer of problems: who audits the algorithm, where the training data comes from, and who is accountable when the machine gets it wrong. These are questions football has not finished answering either, despite being nearly a decade ahead of combat sports.

For Vietnamese combat sports, the moment to act is now, while the market is small and the cost of building standards is low. LION Championship and the national federations can begin with inexpensive measures: archiving scorecards in a standard format, publishing the referee roster before every event, and maintaining a public complaints record so fans can see how the system corrects itself.

Combat sports may never have VAR. But they can absolutely have a database. The remaining question is whether the people running the sport want to look into that mirror, before the next scorecard forces them to.
