V-League and the Crack in Discipline: When a Yellow Card Stands Between Two Deliberate Kicks

On the night of 20 September, on the pitch of Dong Nai, Nguyen Dinh Bac fell twice inside a single passage of play. The first time, the Cong An Ha Noi striker was kicked from behind by Huynh Tan Sinh. The second time, the Dong Nai centre-back repeated the exact same motion, into the exact same leg. Referee Le Vu Linh produced a yellow card. One yellow card for two deliberate kicks at a player without the ball. The whistle did not sound loudly enough, and the silence on the pitch that night did not come from the stands. It came from the distance between what happened and what should have been named. In the same match, in another moment, Dong Nai full-back Le Van Son threw an elbow at Dinh Bac. The ball had already rolled elsewhere; people saw the elbow before they saw the ball. Nobody had to wait for blood to know what they were watching. That is what makes these images hard to forget: they are not ambiguous. They are so clear that ignoring them becomes a conscious choice. Having followed V-League for years, I have noticed something strange about the way people remember violence. Nobody remembers the date. Nobody remembers the score. People only remember the first feeling of helplessness when a player stays down on the grass, and the second, heavier one when they realise the referee has only reached for a yellow. These latest cases do not form a random sequence. They form a repeating pattern. Not long before Dong Nai met Cong An Ha Noi, centre-back Doan Van Hau of Cong An Ha Noi broke the leg of midfielder Doan Ngoc Tan of The Cong Viettel. Also in round two of the 2026-2027 V-League, foreign player Ezequiel Santos Da Silva of Nam Dinh stamped on the stomach of Vo Huu Viet Hoang of SHB Da Nang. Four incidents, two rounds, one season. The phrase on-pitch violence is back in the headlines, and this time it is no longer a hypothesis for idle debate. What stands out is the nature of these moments. A leg-breaking tackle. A stamp to the stomach. An elbow. A kick from behind, repeated twice. These are not collisions of speed, not fifty-fifty duels outside the box. These are acts directed straight at an opponent's body, in positions that have nothing to do with the ball. In the language of the law, this is called violent conduct, and the punishment for it is not a yellow card. What makes these four incidents worrying is not the quantity. Four moments across two rounds, in a league of fourteen clubs, does not sound like much. What is worrying is the pattern: violence is shifting from collisions outside the box towards acts aimed directly at the body, and from spontaneous outbursts towards repeated behaviour. When a player kicks the same opponent twice inside one passage of play, what is happening is not a flash of temper. It is a decision. Faced with that risk, representatives of the tournament organisers, the Vietnam Professional Football Joint Stock Company (VPF) and the Vietnam Football Federation (VFF) met directly with the VFF Referees Committee. In that meeting, the parties demanded that referees apply the law correctly, uphold the discipline of the competition, and prevent violent behaviour on the pitch. The phrase apply the law correctly sounds simple, but it contains something specific: no missed fouls, no missed cards. And this is exactly where the story becomes awkward. Because a missed card had already happened, in the very match the organisers were using as an example. The reminder and the error sit on the same timeline, barely days apart. Referee Le Vu Linh missed a card in the situation where Huynh Tan Sinh kicked at Dinh Bac without playing the ball. He used only a yellow card, not a red, even though the action was repeated twice. This is the technical crux: football law does not only punish behaviour, it distinguishes between acts that are accidents of speed and acts that are choices of intent. A kick from behind, when the player is in control, aimed straight at an opponent's leg while the ball is elsewhere, is not an accident. That it happened twice turns it into a calculated choice. A red card does not make a match worse; it simply names what has already happened. 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 situation. Huynh Tan Sinh kicked a man without playing the ball far too blatantly, but did not receive a red. Lam set out a principle of symmetry, and that principle matters more than any specific sanction: if the player is to be punished retrospectively and suspended for this offence, then referee Le Vu Linh should have his whistle suspended in the same way. Discipline cannot be pressed down onto players alone. If a player errs and is suspended, while a referee errs and is quietly allowed to pass, the system is admitting it is not fair to either side. But the story does not end with one man. Lam raised the role of the VAR team, comprising Vo Hoai Thuong and Nguyen Thanh Son. He laid out two scenarios. Scenario one: the VAR team advised the on-field referee, recommending a red card review, but the on-field referee overruled it. In that case the VAR team did its job, and responsibility lies with the on-field referee. Scenario two: the VAR team gave no advice at all. In that case, the VAR officials must also be dealt with. This way of assigning responsibility is notable because it separates discipline from sentiment. VAR in the V-League is often treated as a black box: nobody knows what was said inside it, and when something goes wrong, nobody is clearly accountable. Lam offers a method of tracing backwards, asking what the VAR team said, in order to find out who stayed silent. A small technical question, but it opens a door to the transparency the V-League has long lacked. Purely in tactical terms, violent conduct tends to appear in teams under pressure, when a gap in quality is compensated for by intensity. Dong Nai hosted Cong An Ha Noi, and in that match the ugliest moments did not come from duels but from passages where the ball had already left the area. It is a familiar pattern: violence does not appear where the match is at its most intense. It appears where the match has already been decided and someone needs to feel in control again. But here is the blind spot few mention: most debates about on-pitch violence stop at the card, while the problem lies elsewhere. A missed card is only the final link in a long chain. Behind a kick from behind lie a congested fixture calendar, accumulated fatigue across rounds, and a must-win-at-all-costs mentality cultivated over many seasons. Violence is not born in a moment. It is born in a system. A counter-intuitive view: when the V-League tightens the screw on referees with the order to apply the law correctly, the risk is that referees will become harsher on moments that do not deserve it, simply to prove they listened. Discipline is not built by increasing the number of cards, but by increasing consistency. What fans want is not more red cards, but a standard applied equally to every team, every round, every name. A yellow in the ninetieth minute for the home side and a red in the ninetieth minute for the away side, for the same act, are two entirely different messages. And there is one more thing. Disciplinary sanctions for referees in Vietnam are rarely made public. Duong Vu Lam revealed how to tell: just watch the referee list for the following rounds and you will 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 that they are being disciplined. A sanction system that the public must guess at through absence, that is discipline you can read but cannot see. And discipline you cannot see is very hard to believe in. This brings us back to an old question: discipline for whom? In football, people usually speak of discipline as something imposed on players. But discipline is really a two-way contract. Players obey the laws of the game, and officials obey the laws of refereeing. When one side breaks the contract without being named, the other loses its reason to comply. That is how violence breeds: not because players are worse, but because they know the limits are being loosened somewhere. I remember standing in the stands once, looking at four empty technical-area seats on the away side after a match full of heavy contact. Afterwards, everything continued. Nobody mentioned anyone. What happened at Dong Nai this time has something of the same quality. People will remember Le Van Son's elbow, remember Huynh Tan Sinh's two kicks, remember Dinh Bac's name. They will mention the referee's name less, and almost never the VAR team's. Football's collective memory always chooses the visible part: a player falling, a ball rolling, a stand reacting. The invisible part, an official's decision, sinks away like a small note in the match report. But if the V-League truly wants to stop violence returning, the invisible part is the part that needs examining. Players will change their behaviour when they know that behaviour is no longer overlooked. Referees will change how they officiate when they know their own mistakes will be named, as transparently as they name players' mistakes. This is why the story of the VAR team matters more than it appears. It is not only about one match. It is a test of whether the V-League truly wants to build a system of discipline, or merely wants to put out a fire burning in front of the public. There is a line I still keep in my notebook, and it remains true of the V-League itself: a pitch does not remember goals, it remembers what people do when nobody is watching. The meeting between the VFF, the VPF and the Referees Committee is a good signal, and signals always deserve acknowledgement. But a signal only has value when it becomes a standard, and a standard only has value when it is applied in the next round, the next match, the next season. Vietnamese football does not lack meetings. What it still lacks is one occasion when everything is called by its right name, and nobody, including the man with the whistle, is allowed to stand outside discipline.
