Huynh Tan Sinh, the tackle from behind and Dong Nai FC's 0-3 defeat

On the evening of September 20, 2026, Công An Hà Nội defeated Dong Nai FC 3-0 at the away ground in round 3 of V-League 2026-2027. The scoreline suggests an easy night for the visitors, but the match will be remembered for something else. In the 78th minute, Huỳnh Tấn Sinh ran behind Nguyễn Đình Bắc and kicked the 22-year-old forward twice in the legs. Đình Bắc lost his balance and fell. The referee showed a yellow card. The ball never lies, but people do. Early in the match, the game changed when Văn Sơn of Dong Nai FC reacted wildly and received a red card after an off-the-ball incident involving Đình Bắc in the 16th minute. Playing with ten men, Dong Nai had to retreat deep. Công An Hà Nội controlled the game, scored three goals, and showed a clear gap in quality. Yet the match is not remembered only for the goals. Tấn Sinh did not try to win the ball. He came from behind, where the player in possession cannot see and cannot react. The first kick made Đình Bắc stagger; the second kick sent him to the ground. This was not a determined challenge. It crossed the line between commitment and violence. After the match, the clip was shared widely on social media. Many fans were furious. One fan wrote: “Tấn Sinh, we are colleagues. Why are you so cruel? You must respect a fellow player’s legs.” Another fan commented: “This is ugly and unacceptable. It was deliberate destruction of an opponent.” Many called for a heavy ban. Huỳnh Tấn Sinh, born in 2026, was a member of Vietnam’s U20 and U23 teams and helped the U23 side win the SEA Games 2026 gold medal. He played for Hà Nội, Công An Hà Nội and Quảng Nam, and was once considered a promising central defender. On September 20, however, people did not remember the glorious Tấn Sinh. They remembered the man who kicked an opponent from behind. Based on my experience following football matches, the most dangerous injuries often come from tackles from behind. When a player attacks from the back, the bodyweight can be dumped onto the knee and Achilles tendon. A player does not need to kick hard to cause serious damage. I have seen a young player miss months of action because of a similar challenge. Football cannot accept such irresponsibility. From a tactical perspective, Dong Nai FC almost collapsed after the 16th-minute red card. Losing a player early forced them to sit deep and absorb pressure. By the 78th minute, frustration had turned into anger. Tấn Sinh lost his composure and made the most dangerous challenge he could. The yellow card immediately became a major controversy. Few people ask why both Văn Sơn and Tấn Sinh lost control against Nguyễn Đình Bắc in the same match. Đình Bắc has skill, speed and a clever way of shielding the ball and waiting for contact. When an attacker keeps getting up and provoking the opponent, the game becomes more than football. It becomes a psychological battle. This does not excuse Tấn Sinh, but it shows that high-level football always has dark areas beyond tactics. I am not defending Huỳnh Tấn Sinh. His action deserves strong criticism and a possible supplementary ban based on video evidence. But punishing one individual will not stop the cycle of violence in Vietnamese football. The real problem is the way clubs educate players to control their emotions. In modern football cultures, players are taught how to challenge safely, when to step back, and how one moment of anger can destroy a season. Hải Phòng taught me that football is an unfinished poem. Unsporting tackles are lines brutally crossed out. Dong Nai fans have every right to be disappointed about the 0-3 loss, but an even bigger disappointment lies in the image of their own team. They can accept a defeat. It is harder to accept seeing their club become the center of ugly incidents. Football always gives us two options: fall or bow your head. On the night of September 20, Dong Nai FC fell in the worst way. There are goals that do not end up in the net but stay forever in memory. The memory of this match will carry two kicks, one yellow card, and a deep question about the boundary between determination and violence. I hope that after this storm of anger, players will understand a simple truth: a colleague’s legs are also their own legs.
