V-League On-Field Violence: The Red Cards That Went Missing in Dong Nai

Minute 68, Dong Nai stadium, September 20. The ball had long left the feet of striker Nguyen Dinh Bac (Cong An Ha Noi). Dinh Bac turned his back and jogged toward his own half. Behind him, centre-back Huynh Tan Sinh (Dong Nai) stretched and swung his boot straight into his opponent's standing leg. Dinh Bac went down. Referee Le Vu Linh produced a yellow card.

Not long before, in the same match, full-back Le Van Son drove his elbow into Dinh Bac's chest during an aerial duel. One victim. Two acts. One yellow card.

Those in the stands saw the ball. Those watching on screen saw the boot. The red card the laws require never appeared.

The incidents did not stand alone. In round 2 of the 2026-2027 V-League, centre-back Doan Van Hau (CAHN) lunged in and broke the leg of midfielder Doan Ngoc Tan (The Cong Viettel). In the same round, foreign striker Ezequiel Santos Da Silva /e.sekjel sɐ̃.tus da siw.vɐ/ (Nam Dinh) stamped on the stomach of Vo Huu Viet Hoang (SHB Da Nang). By the September 20 fixtures, the list had grown longer.

Four incidents. Three rounds. The season has barely begun.

Facing the risk of on-field violence returning and corroding the league's image, representatives of the V-League organising committee, the Vietnam Professional Football Joint Stock Company (VPF) and the Vietnam Football Federation (VFF) met directly with the VFF Referees Committee. The demand was brief: referees must apply the laws correctly, uphold the league's discipline, and stop violent conduct on the pitch.

"Applying the laws correctly" ultimately has one concrete meaning — do not miss fouls, do not miss cards.

The 3F model and the two incidents at Dong Nai

I use a three-layer process to check any incident showing signs of violence: Foul – Field – Frame. Foul asks whether the act constitutes an offence. Field covers positional context: where the ball is, where the player is heading, how far he is from the ball. Frame is the slow-motion angle that shows the contact most clearly.

Apply it to Huynh Tan Sinh's challenge. Foul: the ball was outside both players' control, Tan Sinh had no chance of reaching it, and the kick went straight into his opponent's standing leg. That is playing the man rather than the ball, which falls under violent conduct in Law 12 of the Laws of the Game. Field: Dinh Bac had his back turned and made no attempt to contest; the Dong Nai player actively sought his opponent's leg. Frame: the camera behind the goal shows Tan Sinh stretching to kick twice, not a single collision.

Three layers, three times pointing to the same conclusion: a red card.

For Le Van Son's elbow, the result is no different. The elbow is the body part scrutinised most strictly in aerial duels. When an elbow is aimed at an opponent's upper body while the ball is still in the air, a referee has ample grounds to punish at the highest level.

Referee Le Vu Linh did not do that. He gave Tan Sinh a yellow, ignored the second kick, and did not sanction Son proportionately.

So what did the VAR team do?

This is the decisive link. Under VAR protocol, a missed red-card offence falls into the category of a serious missed incident. In such cases, the VAR team is obliged to recommend that the on-field referee review the situation on the monitor.

Speaking to Dan Tri 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, yet did not receive a red card."

Lam went further: "If Tan Sinh is to be retrospectively punished and suspended for this, then referee Le Vu Linh should have his whistle suspended in the same way. The VAR team's responsibility must also be clarified. If the VAR team advised the referee but was overruled by him, then the VAR team did its job. Conversely, if the VAR team did not advise referee Le Vu Linh that a red card had to be used for the offence described, the VAR officials must also face sanctions."

The two VAR officials in this match, according to match information, were Vo Hoai Thuong and Nguyen Thanh Son.

The point Lam reaches matters more than the card itself: responsibility for a missed decision does not rest with one individual. It is a chain — referee, assistant, VAR team, and the league's governing body. A chain is only as strong as its weakest eye.

Data does not blow the whistle, but it shows where the naked eye misses

Based on my experience tracking matches in the V-League this season, one pattern stands out: violent incidents cluster in the middle third and along both flanks, where movement speed is highest and the distance between players and the ball is most often greatest. It is also the zone where the on-field referee's viewing angle is most easily obstructed.

Pressure on players in these areas grows over the course of a match. As the game wears on, the gap between the lines widens, one-on-one duels multiply, and the probability that a player chooses to solve a problem with his body rather than the ball rises.

In other words, on-field violence does not erupt at random. It has coordinates, a time window, and a degree of predictability. A serious monitoring system would not wait for someone to suffer a broken leg before acting.

The blind spot: refereeing discipline operates in silence

The most visible reaction after the two Dong Nai incidents was a demand that the referees involved be punished severely. I understand that pressure. But there is a paradox: disciplinary rulings against referees in Vietnam are rarely made public.

Duong Vu Lam points to how it works: "Just watch the referee appointment lists for the following rounds to know whether the officials involved have been suspended. If they are not appointed in the rounds immediately after the one just played, the likelihood is they are being disciplined."

A disciplinary system that operates through guesswork from appointment lists produces two side effects. First, it creates no clear deterrent for other referees, because nobody knows where the standard lies. Second, it plants in public opinion the belief that everything is handled according to how loud the media noise is, rather than how serious the error was.

A decision that does not breach the laws can still be wrong in essence; what people need is fairness, not merely accuracy.

The counter-argument: humbling referees does not reduce violence

There is a reflex worth re-examining. When violence appears, the default response is to tighten the screws on referees. But referees handle consequences; they do not create the acts. The player who kicks an opponent's leg is the one who actively chose that act, and sometimes the person who chose it sits on the bench.

Look again at Dong Nai versus CAHN: two different players from the same team, targeting the same opponent, in the same match. Dinh Bac is CAHN's attacking spearhead. Repeated heavy contact with a striker can rob him of rhythm, of confidence, or simply instil fear. If that was a prepared choice, punishing the individual player is not enough; the club also belongs in the disciplinary equation.

People remember the goals; I remember the whistles that protected them. And when the whistle falls silent, football loses its fairness before it loses its appeal.

A public standard is needed

Some situations have no absolutely correct answer, only a decision-maker brave enough to own the responsibility. Tan Sinh's challenge is not one of them. It belongs to the group with a clear answer, and that answer was missed.

A mistake on a live broadcast is like a mistake on the pitch: look it in the eye, learn from it, blow the whistle for the next match. But for that looking to mean anything, it has to be seen. Vietnamese football needs a periodic public report on missed incidents and the sanctions that follow — not to name and shame referees, but to build a standard everyone can read.

The season is long, and the coming rounds will keep testing whether the V-League's discipline is upheld by the laws, or merely by promises.
