From the Elbow at Dong Nai to the Meeting at VFF: V-League Re-Tests Its Discipline

At the Dong Nai versus Cong An Ha Noi (CAHN) match on September 20, the ball had drifted towards the touchline, about ten metres from where Nguyen Dinh Bac was standing. Le Van Son did not chase the ball. The Dong Nai defender chased the man, braced his shoulder, then swung his elbow backwards into Dinh Bac's face and neck, from a position the CAHN striker could not see. Not long afterwards came Huynh Tan Sinh. The centre-back twice lunged from behind, aiming at Dinh Bac's standing leg, in situations where the ball was far away from any contest.

I rewatched that footage several times, freezing frame by frame to check where the referee was standing. Freezing frames does not make me a referee, but it reveals something the human eye struggles to catch on the pitch: once the ball leaves the contest zone, a referee's gaze tends to follow the ball, exactly as it was trained to. Most of the dirty play in professional football happens in precisely that gap — behind the referee's back and behind the crowd's back.

The incidents above did not arrive alone. In round 2 of the 2026-2027 V-League, Doan Van Hau (CAHN) went into a challenge that broke Doan Ngoc Tan's leg (The Cong Viettel). In the same round, foreign player Ezequiel Santos Da Silva (Nam Dinh) stamped on Vo Huu Viet Hoang's stomach (SHB Da Nang). Four incidents, three matches, two rounds. That density was enough to force the organisers to act rather than wait for public opinion to cool.

Representatives of the organising committee, VPF and VFF met the VFF Referees Committee directly. The meeting revolved around one phrase: applying the laws correctly. As those running the league understand it, that includes not missing fouls and not missing cards. The discipline of a league, in its narrowest and most measurable sense, begins with the card.

A missed card happened in the Dong Nai – CAHN match itself. In the incident where Tan Sinh ignored the ball to foul Dinh Bac, referee Le Vu Linh produced only a yellow. He did not use a red, even though Tan Sinh kicked his opponent off the ball twice. Speaking to Dan Tri reporters after the match, former VFF vice-president for technical affairs and former head of the VFF Referees Committee Duong Vu Lam was blunt: "Referee Le Vu Linh missed a card in this incident. Huynh Tan Sinh ignored the ball to foul too blatantly, yet he did not receive a red card."

Lam went a step further. If the disciplinary body issues a retrospective ban on Tan Sinh for that offence, then by the same logic it must also suspend referee Le Vu Linh. The responsibility of the VAR team, made up of Vo Hoai Thuong and Nguyen Thanh Son, also needs clarifying. If the VAR team advised the on-field referee and was overruled, the VAR team did its job. If the VAR team failed to advise that a red card was required for the off-ball foul, the VAR officials must be sanctioned as well.

Disciplinary decisions against referees in Vietnam are usually not published. Lam himself conceded that the only way to tell is to read the appointment lists: if a referee does not appear in the immediately following rounds, he is most likely serving a punishment.

That is the backdrop. What remains is a harder question: why an error falling squarely inside VAR's mandate can slip through, and how large its cost is to the structure of the game.

Under IFAB Law 12, violent conduct does not need the ball to become a red card. Le Van Son's elbow, judged by every criterion the law sets out — force, direction of contact, the opponent's surprise, the ball being elsewhere — belongs in the violent conduct category, where the minimum sanction is a direct red. Huynh Tan Sinh's case sits in a different category with the same outcome. Ignoring the ball to foul is Vietnamese football's shorthand, not a separate article of the law; it describes a challenge with no intention of playing the ball, and once the force exceeds what is necessary, it falls under excessive force or brutality. What matters here is repetition: twice in a single incident turns one foul into a sequence of actions. In a referee's grading framework, repetition is an aggravating factor, the thing that pushes a decision from yellow to red.

So why do misses still happen? Most of the answer lies in the geometry of the pitch. The referee has to manage a vast area of space, and the only way to do that is to follow the ball, because most in-match decisions involve the ball. Off-ball collisions sit at the edge of vision, usually behind the back or in a diagonal blind spot. Assistant referees can catch them when the ball line is close, but when the referee is nearer, assistants tend to defer. That is an operating convention; nobody set a trap on purpose.

The story becomes serious only because the technology already exists. VAR came into full operation in the V-League from the 2026-2026 season according to my records, after a trial phase. The VAR protocol limits intervention to four categories: goals, penalties, mistaken identity and direct red cards. An off-ball foul worthy of a red falls squarely into the fourth. Which means the VAR team does not have to judge the whole match; it only has to answer one narrow question: is this incident a direct red card or not?

The intervention threshold, in the protocol's own language, is a clear and obvious error. That threshold was designed to protect referees from being re-litigated at every minor standard. But that same threshold creates a grey zone: a wrong decision that is not wrong enough to be obvious stands, and nobody is held accountable for the grey zone. Tracking data does not tell you who is right — it tells you who showed up on time. At Dong Nai, the cameras showed up on time. The question is whether anyone is accountable for opening them, and that answer cannot be looked up anywhere.

Football is a game of chess with pawns that can run. Players do not merely run, they calculate. A defender who has been beaten faces two options: let the opponent score, or foul and take a card. If the probability of a red card is low enough, the maths tilts towards the foul. I have no evidence that anyone at Dong Nai calculated this way in those two specific incidents; I am marking this as a hypothesis, not a conclusion. But the incentive structure exists independently of any individual's intent, and it only shifts when the probability of punishment shifts.

One more variable is usually overlooked in debates about on-pitch violence: physical load. Mancini's Italy did not own the ball — they owned the moment. Referees are similar: they do not own the match, they own a handful of decisive moments. Players, in the final 20 minutes, live inside a war of attrition. The five-substitution rule gives squads more depth, but it also stretches the period during which direct duels carry heavy load. Reactions slow, the gap between the standing leg and the point of contact narrows, and late challenges become more dangerous than the same movement in the 20th minute.

I do not yet have enough data to turn that observation into a conclusion for the V-League. Verifying it requires a minute-by-minute distribution of serious fouls across many rounds, not a handful of matches. I do not want to build a pretty number to support a feeling; that is the kind of mistake I remind myself to avoid whenever I sit down at the desk.

One more point deserves attention, and it concerns the victim. Nguyen Dinh Bac is a young striker. In a single match he took an elbow to the head and neck area and was kicked twice from behind on his standing leg. A player's body is still developing at that age, and ankle and knee injuries in that window can follow a career to its end. Vietnamese football has for years relied on pushing young players onto the pitch early, sometimes earlier than their bodies need. The cost of that only shows up in the medical room, years later, when nobody remembers which incident started it.

For the organisers, the damage is commercial. A league's image is what sponsors buy, but it is held together by discipline. A league where dirty play is only addressed after public outrage will force the people paying the bills to reprice their contracts. Sponsors do not care who was right in a challenge; they care whether that clip shows up on international bulletins.

This is where I want to push against the common reflex.

The familiar reflex after every incident is to demand a suspension. Referee Le Vu Linh missed a card, the VAR team stayed silent, so punish both. The demand sounds reasonable, and in a transparent system it is entirely normal. But it has a blind spot: punishing referees does not change a player's calculation. The only thing that changes a player's calculation is the certainty of punishment directed at the player — fast, public, and consistent across rounds. If a defender believes violent conduct reliably brings a multi-match ban, that conduct disappears from the option list. If a defender believes the chance of being caught is fifty-fifty, it stays on the list.

Deeper down there is a problem with how information is published. Player sanctions are announced widely; referee sanctions are not, and the only way to guess is to read the appointment lists. That asymmetry accidentally teaches the public a habit: reading silence as cover-up. A reasonable disciplinary decision kept secret still generates more suspicion than a questionable one that is explained. Transparency is not merely an ethical matter; it is a communications risk-management tool.

There is another rarely mentioned risk: tightening demands without changing the review mechanism can push referees towards defensive behaviour, brandishing more cards to prove they are strict. Matches fragment, card counts rise, and the referee becomes the main character. Pressure without a published standard only turns inconsistency into inconsistency in the opposite direction.

So what should be watched next week? The referee appointment list. If Le Vu Linh and the VAR team do not appear for several rounds, the system has handled it in the familiar, silent way. If they are still appointed, fans will draw their own conclusions, and those conclusions rarely favour the league. The real test for the V-League is not a single disciplinary ruling, but whether the standard holds from round 3 to round 13. A league that is only strict for three rounds is not strict; it is simply waiting for the crowd to turn away.
