V-League 2026-2027 On-Pitch Violence: When Referees Miss Cards, League Discipline Faces Its Test

In the match between Dong Nai and Cong An Ha Noi on 20 September, there was a moment that anyone watching only the highlights would miss. Nguyen Dinh Bac released the ball and turned away. The ball had already gone. Huynh Tan Sinh's leg did not follow the ball. First time. Then a second time. In the same match, defender Le Van Son threw an elbow at Dinh Bac. Two different actions, one target, one match, one player on the receiving end.

I rewound that footage four times and muted the commentary. With the commentary off, what remains is the sound of studs biting into grass, the sound of breathing, the whistle. Then a yellow card is produced.

That yellow card is the beginning of everything that follows.

One match, two incidents, four events in a single sequence

To understand why the league organisers sat down with the VFF Referees Committee, the Dong Nai versus CAHN match has to be placed inside its timeline. Round 2 of the 2026-2027 V-League season produced two serious incidents: defender Doan Van Hau of Cong An Ha Noi broke the leg of midfielder Doan Ngoc Tan of The Cong Viettel, and foreign player Ezequiel Santos Da Silva of Nam Dinh stamped on the stomach of Vo Huu Viet Hoang of SHB Da Nang.

Not long afterwards, the Dong Nai versus CAHN match on 20 September added two more: Le Van Son's elbow on Nguyen Dinh Bac, and Huynh Tan Sinh repeatedly kicking from behind at Dinh Bac's leg.

Four incidents in a short window. That is when the phrase pitch violence returned to the headlines, and when representatives of the tournament organisers, VPF and VFF met directly with the VFF Referees Committee. The demand was specific: referees must apply the laws correctly, maintain the league's discipline, and stop violent conduct on the pitch.

Applying the laws correctly, in its most practical reading, means missed fouls and missed cards cannot be allowed to happen.

And that is exactly what happened at Dong Nai versus CAHN.

Referee Le Vu Linh and the incident where Tan Sinh kicked Dinh Bac off the ball

In the phase where defender Huynh Tan Sinh went for the man rather than the ball against Dinh Bac, referee Le Vu Linh used only a yellow card to punish Tan Sinh. He did not produce a red card, even though Tan Sinh struck Dinh Bac off the ball twice.

Speaking to a Dan Tri reporter after the match, former VFF vice-president for specialist affairs and former head of the VFF Referees Committee Duong Vu Lam was blunt: “Referee Le Vu Linh missed a card on this incident. Huynh Tan Sinh's challenge off the ball was far too obvious, yet he was not given a red card.”

Duong Vu Lam went further and questioned the symmetry of the punishment: “If Tan Sinh is to be retrospectively banned for this, then referee Le Vu Linh must be suspended in the same way. The responsibility of the VAR team must also be clarified. If the VAR team — comprising Mr Vo Hoai Thuong and Mr Nguyen Thanh Son — advised the on-field referee but was overruled, then the VAR team did its job.

Conversely, if the VAR team did not advise referee Le Vu Linh that a red card was required for the off-the-ball challenge described, then the VAR referees must also be sanctioned.”

That statement carries weight because it does not stop at identifying one individual's error. It identifies the accountability structure behind the error.

Disciplinary decisions against referees are normally not published. But according to Duong Vu Lam, there is still a way to tell: “Just watch the referee appointment lists in the following rounds and you will know whether the referees involved have been suspended. If they are not appointed in the rounds immediately after the round just played, the likelihood is that they are being disciplined.”

This is a small detail with real verification value. It turns a closed process into publicly trackable data.

Going for the man: the action that is invisible on television

I drew the diagrams for this match by hand, on paper, the way I have since 2026. A hand-drawn diagram from the 2026 World Cup can still read tonight's match. And when I draw, the first thing I record is not the position of the ball, but the space behind the receiver's back.

The crowd watches the stars; I watch the space behind them. In Tan Sinh's phase, the ball had already been released in another direction. The broadcast camera, by habit, follows the ball. Viewers see the ball. Viewers do not see Tan Sinh's leg.

That is why this category of offence is hard to catch with the naked eye. It happens in what I call the dark zone of the frame. It only becomes visible when someone actively rewinds, slows the footage down, and separates sound from image. I hear the studs hitting the shin, not the ball. The ear catches what the eye has already skipped.

Tactics are not magic. It is just that some people look a little longer.

Geometrically, a typical off-the-ball challenge has three features. First, the distance between the ball and the point of contact usually exceeds one metre, sometimes two. Second, the direction of the offending player's movement is not towards the ball but towards the opponent's body axis. Third, the timing of contact falls when the on-field referee is at a diagonal angle, screened by players' bodies.

Those three features combine to produce a structured blind spot, not a random mistake. A structured blind spot can be compensated for by a system. And the only compensating system modern football has is VAR.

VAR is not a security camera, it is a decision-making process

Many people imagine VAR as a camera that sees everything. That image is wrong operationally. VAR intervenes only in four defined categories: goals, penalty kicks, direct red cards, and mistaken identity. Within the direct red card category, VAR has both the right and the duty to recommend that the on-field referee review the incident.

That creates the chain of questions Duong Vu Lam put so concisely. Did the VAR team see the incident? If it saw it, did it make a recommendation? If it recommended, did the on-field referee overrule it? Each answer leads to a different conclusion about responsibility.

If the VAR team recommended and the on-field referee overruled, responsibility sits with the on-field referee. If the VAR team stayed silent, responsibility sits with the VAR team. There is no scenario in which responsibility simply disappears.

This is the point I consider most important in the whole story, and also the point most easily skimmed over when people argue about pitch violence.

Why pitch violence arrives in clusters, not evenly spread

Data does not lie, but it is good at hiding surprises. When I logged the four incidents in this sequence, what stood out was not the severity of any single challenge. What stood out was that they arrived as a cluster.

In football, fouls have two very different origins. The first is the tactical foul: fouling as a tool to stop a counter-attack, to break an opponent's rhythm, to buy time for a defensive line to reorganise. This kind of foul has logic, calculation and is measurable.

The second is the retaliatory foul, which appears when a player feels he cannot compete by playing football. This kind has no tactical logic. It is the product of lost composure, or of a team that has already abandoned its defensive structure.

When a league goes through many matches with large gaps in quality, when weaker teams are pinned back and starved of the ball, the second source grows. Players cannot win the ball with their feet, so they win it another way. That is a mechanism, not an excuse.

In other words, pitch violence is not purely a question of individual morality. It is a question of match structure. And match structure can be adjusted through league governance.

The blind spot is that punishment is not symmetrical

The counter-intuitive point I want to make is this: if the organisers sanction players but not referees, the league's discipline will not improve. It will merely shift location.

The reason is simple in incentive terms. A player calculates that if he kicks an opponent off the ball, retrospective punishment is possible, but immediate punishment on the pitch is unlikely. If the probability of immediate punishment is low, the expected cost of the action falls. And when the cost falls, the behaviour rises.

This is where Duong Vu Lam's remark becomes significant: if players are retrospectively banned, referees must be treated similarly. He did not say this as an emotional comparison. He said it as an operating principle.

In a refereeing system, referee error and player error are two faces of the same problem. Punish only one side, and the other side will not change its behaviour. And if the side that does not change is the side holding the power to stop the match, every other reform gets blocked at that point.

This also explains why referee sanctions are usually handled quietly. Quiet handling protects the referee's authority in public. Its major drawback is that it cancels the deterrent signal. If nobody knows the punishment, the punishment produces no new behaviour.

Duong Vu Lam hinted at an indirect way to read referee appointment lists. It is a clever solution, but it is also evidence that the system lacks transparency at precisely the point where transparency matters most.

Lessons from public corrections

I have made a data error and corrected it publicly. In 2026, analysing Morocco's defence, I misstated a figure on aerial duel success. I deleted the post, rewatched the footage, and republished a corrected version within two hours, opening with a clear note on where the error lay. Readership doubled after that.

That experience taught me something applicable to this story: transparency in correction builds credibility far more than silence protects a position.

If the VFF Referees Committee published its conclusion on the Tan Sinh incident, disclosed whether the VAR team made a recommendation, and stated the specific sanction, fans' trust in the refereeing system would rise, not fall. A closed process, by contrast, turns every debate off the pitch into speculation, and speculation always disadvantages the party under suspicion.

The former head of the VFF Referees Committee said out loud something many people in the game know but few put into words. That he said it, at this particular moment, carries the same value as a public correction.

Why I still draw diagrams by hand

I do not draw with an app; I draw by hand as I did in 2026. Not because of any weakness in technology, but because drawing by hand forces me to understand. When lines are produced by a hand, the drawer cannot hide ambiguity behind an effect. The hand must decide every player's position, and every decision must have a basis.

That is why I always begin analysing a match with a question about distance. When a team loses the ball, how many metres does the block compress? How far apart are the midfielders and the forwards? In the phase that led to Tan Sinh's off-the-ball challenge, the distance between Dong Nai's defensive line and the ball had stretched beyond reasonable reach. When that distance cannot be covered by speed, players choose to cover it with contact.

Those questions are less appealing than asking which team deserved to win. But they explain why an ugly action appeared at one specific moment, committed by one specific player.

People have asked what a girl knows about football to speak with such authority. I showed them a pressing trap. Years ago, when an account commented that a girl knows nothing about football and should not lecture, I did not reply. I simply added a chart of each player's average position to the article.

Data is my shield. And in this story about pitch violence, data is also the shield for everyone who wants the league's discipline enforced in its true sense.

What to watch in the next round

There is a very concrete way to verify this entire story, and it is not found in accusations or commentary. It is found in the referee appointment list for the next round.

If referee Le Vu Linh does not appear on the appointment list, that is one signal. If the two VAR referees Vo Hoai Thuong and Nguyen Thanh Son are absent, that is another. If all three are appointed as normal, we have a third signal, and that third signal says a great deal about how the league understands the phrase applying the laws correctly.

No statement is needed. The referee appointment list is the most transparent statement a football league issues each week; it is just not read that way.

The match does not end at minute 90; it ends when I find the pattern. With this sequence of events, the pattern has not closed. It is waiting for an administrative decision, and that decision will teach the whole league what the price of violent conduct on the pitch actually is.

For me, the question is no longer who was wrong in a single phase of play. The question is whether the system has the courage to be wrong and to correct itself publicly, or whether it will keep choosing silence and hope the audience forgets before the next round.
