Dong Nai night: Tan Sinh's kick, controversial yellow card and Cong An Hanoi's 3-0 victory

On the evening of September 20, Cong An Hanoi beat Dong Nai City Club 3-0 at the home ground of the latter in round 3 of V-League 2026-2027. The scoreline, however, does not tell the whole story. The match was marked by a red card in the 16th minute, a controversial foul in the 78th minute and a wave of anger from fans after videos of the incident were widely shared. The first turning point came early. In the 16th minute, Van Son of Dong Nai City was sent off after striking Dinh Bac off the ball. Playing with one man down for almost 75 minutes, the hosts struggled to keep their shape. Cong An Hanoi used the numerical advantage to score three goals, keep a clean sheet and take all three points. But the most discussed moment was neither a goal nor the early red card. In the 78th minute, with Cong An Hanoi leading 3-0, Dinh Bac controlled the ball in midfield. Tan Sinh came from behind and delivered two consecutive kicks at the 22-year-old forward's legs. The first kick made Dinh Bac stumble. The second made him fall to the ground. Referee immediately awarded a foul and showed Tan Sinh a yellow card. Many fans thought the punishment was too light. One fan wrote: “Tan Sinh, we are colleagues. Why are you so cruel? You must respect your colleague's legs.” Another wrote: “This is too ugly and unacceptable. It was an intentional attempt to take down the opponent.” Some even called for a heavy suspension, saying that such dangerous conduct would continue if not properly punished. Huynh Tan Sinh, born in 2026, is a former member of Vietnam's U20 and U23 teams. He was part of the U23 squad that won the gold medal at SEA Games 2026. At club level, he has won V-League titles with Ha Noi FC, Cong An Hanoi and Quang Nam. That background makes the incident more regrettable. The match also raised broader questions about discipline, refereeing standards and player safety in Vietnamese football. In modern football, tackles from behind, especially those aimed at an opponent's standing leg, are treated very seriously. Video review and post-match discipline have become powerful tools to protect players. V-League still has room to improve in this area. For Cong An Hanoi, the victory was important. For Vietnamese football, the lasting lesson from September 20 is not limited to the score. It is about controlling emotions, respecting opponents and keeping the game safe. A civilized football culture is measured not only by titles, but by how players treat each other on the pitch.
