Following the match between Vietnam and Thailand in the FIFA ASEAN Cup 2026, forwards Nguyễn Đình Bắc and midfielder Lê Phạm Thành Long were required to undergo doping control. This standard procedure involves testing for prohibited substances after international fixtures. Both players will remain for examination as part of the protocol established by the tournament organizers. The selection of Đình Bắc and Thành Long for testing doesn’t automatically indicate a positive finding, but rather a routine check. Results from the doping control will be analyzed in accordance with FIFA regulations. The Vietnam national team will continue preparations for future matches within the FIFA ASEAN Cup 2026 qualification process.
