V-League on-field violence: Law 12.3 and the two missed cards in Dong Nai vs CAHN

The ball was metres away. There was no challenge, no tackle, no attempt to play it. Huynh Tan Sinh, the Dong Nai centre-back, walked up and kicked Nguyen Dinh Bac in the back of the leg. Referee Le Vu Linh blew his whistle and produced a yellow card. The stand rose for a single beat and fell quiet again. Dinh Bac got up, limped a few steps, and carried on. That was Dong Nai against Cong An Ha Noi (CAHN) on 20 September 2026. In the same match, defender Le Van Son threw an elbow at Dinh Bac. Two different acts, one shared detail: neither was aimed at the ball. Soon afterwards, representatives of the V-League organisers, VPF and VFF met the VFF Referees Board in person. The message came down to four words: apply the Laws correctly. For the league's administrators, that phrase means no missed fouls and no missed cards. The discipline of the V-League, in their framing, is being worn down by exactly the sort of incident nobody punished. The risk did not come from a single match. In round 2 of the 2026-2027 V-League, centre-back Doan Van Hau (CAHN) went into a challenge that left midfielder Doan Ngoc Tan (The Cong Viettel) with a broken leg. In the same round, foreign striker Ezequiel Santos Da Silva (Nam Dinh) stamped on the stomach of Vo Huu Viet Hoang (SHB Da Nang). Then came Dong Nai with two more: Le Van Son's elbow and Huynh Tan Sinh's two off-ball kicks at Dinh Bac. Four incidents, four different players, all inside a short window. What stands out is how differently they were handled. On the Tans Sinh incident, referee Le Vu Linh used only a yellow card, even though the centre-back kicked Dinh Bac twice. That is the point former VFF vice-president for professional affairs and former head of referees Duong Vu Lam called a missed sending-off. Speaking after the match, Lam said: "Huynh Tan Sinh kicked the man so blatantly, yet he was not sent off." To understand why that sequence requires a red card, open Law 12 of the IFAB Laws of the Game. Law 12.1 establishes that kicking or attempting to kick an opponent is a foul punished by a direct free kick. Law 12.3 lists the sending-off offences, and two entries there are routinely skimmed over: serious foul play and violent conduct. The line between those two entries rests on a single question: is the player attempting to challenge for the ball? A challenge with force exceeding what is necessary is serious foul play. Excessive force with no challenge at all is violent conduct. Both carry a direct red card. A yellow card is not a lighter version of a red. It is a different provision, written for reckless conduct that still happens inside a football challenge. When a player kicks an opponent's leg while the ball is metres away, a yellow card stops being a lenient option. It becomes the wrong provision. Fans remember the goals; I remember the clauses. In the Tans Sinh case, the decisive fact is the distance between his boot and the ball. There was no challenge to speak of, so there was no force threshold to debate. That he kicked twice in the same sequence only clarifies intent; it does not change which provision applies. The Le Van Son incident sits in the same bracket. An elbow with no ball to contest, directed at an opponent's head, falls inside the definition of violent conduct. In round 2, the Doan Van Hau and Ezequiel Santos Da Silva incidents raised the same questions about excessive force and player safety. What the league's organisers are chasing is consistency: the same provision, applied the same way, regardless of the name on the shirt. In the Tans Sinh case, a second question belongs to the VAR team. The VAR protocol attached to the Laws of the Game allows technology to intervene in four categories, one of which is a direct red card. An off-ball kick that can produce a direct red card falls squarely inside the reviewable category. The VAR team of Vo Hoai Thuong and Nguyen Thanh Son therefore had both the authority and the duty to check it. Duong Vu Lam frames the question in two branches. If VAR advised the referee and the referee overruled it, VAR did its job. If VAR did not advise, the VAR officials should face sanctions too. Reviewing footage is not a sign of mistrust; it is how the truth gets respected. The same logic leads to Lam's most pointed suggestion: if Tans Sinh is banned retroactively for this foul, referee Le Vu Linh should be stood down in the same manner. That is a symmetry argument, and it touches something rarely discussed: disciplinary rulings against referees are usually not published. Lam suggests a way to read the tea leaves. Watch the referee appointment lists for the following rounds. If an official does not appear in the round immediately after the one in question, the likely explanation is a sanction. A mistake is a footnote; only silence becomes a verdict. The blind spot sits elsewhere. When violent conduct goes unpunished, what is lost is not merely a card. What is lost is the price of the act. A player who calculates that an off-ball kick can buy three points, with a yellow card as the worst realistic outcome, will keep kicking off the ball. In the other direction, a referee who knows every decision will be picked apart may reach for cards faster than the game requires, turning a physically contested league into a string of broken matches. An instruction to apply the Laws correctly is easily translated into showing more cards. Those are not the same thing. What the V-League needs is a clearly defined threshold applied the same way across an entire season, not a strictness campaign lasting a few weeks. Based on my experience following matches in this league across several seasons, clean-up drives that begin with a meeting usually end with cards. The cheapest form of verification is not the card count but two publishable items: the audio of the exchange between the referee and the VAR team, and a referee discipline table released the way player suspensions are. With those two in place, the phrase apply the Laws correctly becomes checkable. For now, watch the referee appointments for the next round. One absent name will say more than any press release. A match can be paused, but the responsibility of the man with the whistle cannot.
