Violence in V-League: Tan Sinh, Van Hau and the Days Discipline Was Tested

Referee Le Vu Linh raised a yellow card. Huynh Tan Sinh turned and walked away. A few metres behind him, Nguyen Dinh Bac was still on the grass, both hands around his right calf. The stands at Dong Nai stadium roared. The match between Dong Nai and Cong An Ha Noi on 20 September carried on, but on replay one detail became unmistakable: the ball had long gone, and the second kick still arrived.

That detail separates the incident from an ordinary collision. Centre-back Huynh Tan Sinh kicked Dinh Bac's leg twice. The first could be argued as intent. The second cannot, because the ball was gone, the player was down, and the boot still came. Earlier in the same match, defender Le Van Son threw an elbow at striker Nguyen Dinh Bac. Three actions aimed at one player inside ninety minutes, and the number of red cards shown was zero.

For anyone who watches professional football closely, this is the worst kind of image a league can produce: a young player on the ground, a referee surrounded by protests, and a VAR team somewhere in a sealed room whose voices the public never hears. I watched that footage repeatedly. The slower I played it, the clearer the gap between the second kick and the moment the ball left.

Four incidents in two rounds

Not long before Dong Nai hosted Cong An Ha Noi, V-League 2026-2027 had already endured two shocking incidents in round two. Centre-back Doan Van Hau of Cong An Ha Noi broke the leg of midfielder Doan Ngoc Tan of The Cong Viettel. In another match in the same round, foreign striker Ezequiel Santos Da Silva of Nam Dinh stamped on the stomach of Vo Huu Viet Hoang of SHB Da Nang.

Those two were enough to raise questions about the league's discipline. By 20 September, when Le Van Son threw his elbow and Huynh Tan Sinh kicked Dinh Bac twice, the questions turned into pressure. Four incidents in two rounds, three of them aimed at attacking players, and one shared feature: the victim is the one left limping or carried off, while the punishment is lighter than the footage suggests.

The wider context matters too. V-League entered the 2026-2027 cycle with heavier commercial pressure, a denser calendar, and a generation of young players pushed onto the pitch early. When the value of a point rises, the value of neutralising an opponent rises with it.

There is a distorted calculation here that rarely gets named. A cold kick at an opposing striker's leg can cost him weeks or months, while the immediate price on the pitch is a yellow card, or even just a free kick. Judged as an investment, the behaviour offers a positive return. That is precisely why serious leagues have to create a far heavier price afterwards.

The meeting at VFF and the phrase 'apply the laws properly'

After the sequence of incidents, representatives of the organising committee, the Vietnam Professional Football Joint Stock Company (VPF) and the Vietnam Football Federation (VFF) met the VFF Referees Committee directly. According to what was made public, the meeting centred on a demand that referees apply the laws properly, preserve the league's discipline, and stop violent behaviour on the pitch.

'Apply the laws properly' sounds like an administrative order. Read closely, it is a confession. In football, telling referees to apply the laws properly is equivalent to admitting that at certain moments the laws were not applied. The phrase also shows that the administrators know where the weakness sits: not in the absence of rules, but in missed fouls and missed cards.

That is exactly what happened at Dong Nai. In the incident where Huynh Tan Sinh played the man instead of the ball against Dinh Bac, referee Le Vu Linh used only a yellow card, even though the centre-back kicked his opponent off the ball twice. No red card was produced for conduct the footage suggests was deliberate.

Speaking to Dan Tri reporters after the match, former VFF vice-president for professional affairs and former head of the VFF Referees Committee, Duong Vu Lam, was blunt: 'Referee Le Vu Linh missed a card in that incident. Huynh Tan Sinh played the man far too blatantly, but was not sent off.'

Lam went a step further than most insiders dare. 'If Tan Sinh is punished retrospectively and suspended for this, then referee Le Vu Linh should have his whistle suspended in the same way. Beyond that, the responsibility of the VAR team must be clarified.'

The insider knows too much, but only the outsider dares to say it. Duong Vu Lam once sat in the chair that manages referees, once signed the appointment lists, and therefore knows exactly what the price of a missed card looks like backstage.

Where Law 12 went wrong

To judge a decision, separate two questions: what the referee saw, and which category he placed the action in. In Tan Sinh's case the first is barely disputed: the ball was no longer in anyone's control when the second kick arrived. The second is where the problem begins.

Law 12 of the Laws of the Game draws a clear line between two families of offences. The first covers careless, reckless and excessive-force challenges, which lead to a direct free kick and normally a yellow card. The second covers violent conduct, which leads to a red card. The dividing line is whether the action was connected to a challenge for the ball. A kick while contesting the ball is a foul. A kick after the ball has gone is violent conduct, and the mandatory sanction is a red card.

Referee Le Vu Linh showing only a yellow card indicates he classified Tan Sinh's action as excessive force. That is a classification error, and it matters more than an identification error. A referee can missee, can be blocked, can have his view crowded. But once the footage shows two kicks, keeping the sanction at yellow means the whole system overlooked the nature of the act.

One small but weighty detail: in the same match, Le Van Son threw an elbow at Dinh Bac. An elbow is the clearest category of violent conduct in Law 12. If a single match produces two violent-conduct acts and no red card, the problem is no longer one isolated incident.

Fairness also requires a word for the referees. They work under conditions where every decision is reviewed at a fraction of real speed. A professional culture that prizes 'managing the game' through soft yellow cards to keep the temperature acceptable will naturally push officials toward leniency. But systematic leniency creates a bigger problem: it signals to both teams that the referee's tolerance threshold has been lowered.

The VAR team and the limits of 'clear and obvious'

The Video Assistant Referee was designed to intervene in four categories: goals, penalties, direct red cards, and mistaken identity. A missed red card sits squarely in the third. In other words, the Tan Sinh incident is exactly the kind of case VAR exists to handle.

But VAR only intervenes when there is a clear and obvious error, or when a serious incident has been missed by the on-field team. That clause is among the vaguest in modern football law, because clear and obvious is not a measurement, it is a judgement. Two people watching the same slow-motion clip can reach two different conclusions, and both can believe they are right.

I have spent many sessions re-watching VAR incidents in Ligue 1 and noting the exact moment each decision was made, purely to compare it with how public opinion reacted afterwards. That experience taught me that the subjective space inside VAR is far wider than fans imagine. Technology removes errors of sight, not errors of interpretation.

At Dong Nai, the VAR team consisted of Vo Hoai Thuong and Nguyen Thanh Son. Former VFF referees chief Duong Vu Lam set out two scenarios with opposite consequences. If the VAR team advised the on-field referee and was overruled, then the VAR team did its job. Conversely, if the VAR team failed to advise that a red card was required for the off-the-ball kick, then the VAR officials must also face sanctions.

That framing is technically correct, and it exposes a larger hole: neither scenario can be verified from the outside. Fans never hear the exchange between the referee and the VAR room. Journalists never see the log. So whether VAR advised becomes a fact that exists only behind a closed door, and judging it depends on the goodwill of the very people involved.

The summer of 2026 taught me this: silence means everything is being compressed. In football, a silent VAR room does not mean nothing happened. It only means we have not been allowed to hear it.

Punished in public, punished in silence

Under the current disciplinary system, players pay publicly. If Tan Sinh is punished retrospectively, his name appears in the disciplinary committee's document, the length of suspension is published, news sites pick it up. The player pays in front of the entire audience.

For referees, the mechanism runs differently. Specific sanctions against referees are usually not widely announced. As Duong Vu Lam revealed: 'Just watch the referee appointment list for the following rounds and you will know whether the officials involved have had their whistles suspended. If they are not appointed in the rounds immediately after the one just played, there is a strong chance they are under sanction.'

There is a professional rationale. Referees work under immense pressure, and publishing verdicts can turn them into long-term targets for home crowds. But the flip side of discretion is the loss of deterrence. A punishment nobody knows about cannot establish a standard. It changes the behaviour of one person for one period, and sends no message to anyone else.

The result is an asymmetry: a suspended player is known nationwide, a suspended referee is only guessed at by those who read the appointment lists closely. For a league trying to prove it is serious about violence, that asymmetry neutralises the very message the organisers want to send.

The blind spots of the official story

The fashionable framing is this: on-field violence is rising, so referees must be stricter. That framing pushes the story toward individual refereeing competence and ignores three larger blind spots.

The first is the role of retrospective punishment. When the disciplinary committee can act after the match, the system has two routes to correct errors: on the pitch and after it. That sounds sensible, but it creates a structure that rewards hesitation. If a violation can always be handled later with video, the pressure to get the decision right in the moment drops. The better the safety valve, the easier the pot boils over.

The second is the selection criterion. The Van Hau and Ngoc Tan incident drew attention for the severity of the injury. The Ezequiel and Viet Hoang incident drew attention for the image. The Tan Sinh incident drew attention because the victim was Dinh Bac, a name the media is chasing. Three cases, three different speeds of response, and the real criterion for the difference is broadcast reach, not the seriousness of the act.

The third is that justice depends on the number of cameras. Not every V-League match has the camera coverage of Dong Nai versus Cong An Ha Noi. In matches with fewer angles, an elbow may never exist in any record at all. A disciplinary system built on footage accidentally constructs a form of justice that is inversely proportional to the number of recording devices.

One more thing must be said about the philosophy referees always cite when challenged: minimum interference, maximum benefit. It was designed to protect the flow of the game, so VAR does not turn every phase into a trial. But it only makes sense when the intervention threshold is clearly defined. When that threshold is pushed too high, VAR becomes a tool that works only in undeniable cases, and every grey-area incident returns to the judgement of one person on the pitch. That is the paradox of minimum interference: it protects the authority of the on-field referee, not the safety of the players.

In modern football, clubs no longer buy players, they buy stories. Violence, unfortunately, is a story that sells. A collision shared hundreds of thousands of times generates engagement a 1-0 win cannot. The pressure that forces a league to act therefore depends on how fast the story spreads, not on how serious it is.

What to watch in the coming rounds

Some indicators can be verified with the naked eye, without waiting for an official document.

The referee appointment list is one of them. The absence of referee Le Vu Linh, or of the officials in the VAR team at Dong Nai, will say more than any statement from the organisers.

The disciplinary ruling on Huynh Tan Sinh is another. If the committee identifies an off-the-ball kick and suspends the Dong Nai centre-back, then logically the same footage is sufficient grounds to examine the responsibility of those who failed to show a red card. The gap between those two conclusions is the measure of discipline.

And there is a larger question Vietnamese football has never answered: when will fans be allowed to hear the exchange between the referee and the VAR room? In many leagues, publishing VAR audio has become part of transparency practice. Until that happens, the VAR room remains a black box, and every conclusion about responsibility stays at the level of guesswork.

I write for those rarely listened to, so I always ask about the worst case. Dinh Bac was fortunate because he is a player people pay attention to, with cameras, with his name in the news, with a former referees chief speaking on his behalf. But a striker at an unfashionable club, on a pitch with two cameras, kicked twice and left to get up alone: who will rewind the footage for him?

That is the final limit of every meeting about discipline. A disciplinary culture is only credible when it protects the people nobody films.
