Missed Red Card in Dong Nai vs CAHN: V-League Discipline Kept by Referee Appointments

The ball had already gone elsewhere. Nguyen Dinh Bac had just released it, his body still angled forward, when Huynh Tan Sinh came in from behind and kicked into the striker's leg. It was not a single act. The Dong Nai centre-back repeated the same motion during the match on September 20, 2026. Earlier in that same game, defender Le Van Son threw an elbow toward Dinh Bac.

Three incidents, one victim, one match. Referee Le Vu Linh showed a yellow card to Tan Sinh. There was no red card.

Based on my experience watching matches, this is the type of situation where the human eye always arrives late: the ball has left the offender's foot, so there is no challenge left for the gaze to lock onto. Off-ball violence is a structural blind spot for every refereeing department, not only Vietnam's V-League.

What makes it worrying is that these cases do not stand alone. In round 2 of the 2026-2027 V-League season, Doan Van Hau (CAHN) broke the leg of Doan Ngoc Tan (The Cong Viettel). In the same round, foreign player Ezeqiuel Santos Da Silva (Nam Dinh) stamped on the stomach of Vo Huu Viet Hoang (SHB Da Nang). Days later it was Dong Nai's turn, with two incidents aimed at the same player.

The governing bodies responded quickly. Representatives of the tournament organisers, VPF and VFF met directly with the VFF Referees Board. The message was narrow: referees must apply the laws correctly, protect the competition's discipline, and stop violent conduct on the pitch.

Applying the laws correctly means something very concrete here: no missed fouls, no missed cards. The discipline of a league is not built in post-match sanctions; it is built in the moment a referee stands five metres from the incident and must decide within two seconds. Every mechanism behind him is correction, not prevention.

There are two layers of responsibility in Tan Sinh's challenge. The first is the main referee. The second is the VAR team. Former VFF Vice President for football affairs and former head of the VFF Referees Board, Duong Vu Lam, told Dan Tri: "Referee Le Vu Linh missed a card in that incident. Huynh Tan Sinh's kick off the ball was too blatant, yet he did not receive a red card."

Lam then inverted the league's usual logic: "If we hand out a retroactive ban to Tan Sinh for this foul, then referee Le Vu Linh must also be suspended in the same way." He pushed the matter to a third layer: the responsibility of the VAR team, comprising Vo Hoai Thuong and Nguyen Thanh Son. If VAR advised the referee and was overruled, the team did its job. If VAR stayed silent on a clear off-ball kick, those officials must also face sanctions.

The central point is this: a missed red card is not the failure of one individual, but the output of a decision chain in which every link can be audited. That is the difference between modern football and the game of twenty years ago. With VAR in place, the referee is no longer the only person who sees. He remains the only person who decides, but he is no longer the only person accountable.

The problem in the V-League is that the chain breaks at the point of disclosure. Disciplinary measures against referees are rarely announced publicly. Duong Vu Lam pointed to the indirect way of checking: "Just watch the referee appointments in the following rounds. If the officials involved are not assigned to the rounds immediately after the one just played, the likelihood is that they are being disciplined."

In other words, the only tool the public has to measure the league's discipline is an inference drawn from absence. No document, no announcement, only a gap in the appointment list. In a competition where refereeing controversy is the hottest topic after every round, allowing discipline to exist in silence is a design choice, not an operational accident.

The debate is being pushed along one axis: heavier sanctions, more suspensions, stricter rulings. Look at the structure, though, and that axis has a blind spot.

When players know that every ugly incident will be judged afterwards on video, and when referees know that every decision will be reviewed, the natural response on both sides is to shift risk rather than reduce it. Players learn to foul where the eye cannot reach — behind the referee, after the ball has gone. Referees learn to manage cards by their own margin of safety.

What stands out is that both incidents in Dong Nai targeted the same player, both came from behind, and both occurred after the ball had left the foot. This is a behavioural pattern, not an accident. Modern football violence does not happen inside the challenge; it happens in the gap immediately after the challenge ends. And that gap is where the human eye, the VAR eye and even the wide camera angle are weakest.

Before trusting my own eyes, I choose to trust structure. Structure will answer within the next few rounds, through an appointment list. If Le Vu Linh and the VAR team from the Dong Nai versus CAHN match are absent in the following round, discipline was upheld, just upheld in silence. If they appear again, every meeting between VFF, VPF and the Referees Board was only a meeting.

Data never shouts, but it whispers loudly enough for anyone willing to listen. And the question left for the next round is this: is the league protecting its players, or protecting its fixture list?
