In the 6th minute of the match between U23 Vietnam and U23 Kuwait on the evening of April 17, Dinh Bac suffered an ankle injury after attempting to tackle the ball. Although he tried to continue playing, he could only play for 3 more minutes before signaling for a substitution. Coach Hoang Anh Tuan was forced to send Van Truong in to replace Dinh Bac.

On the afternoon of April 18, Dinh Bac shared on his personal page about his injury: Accordingly, the player from Quang Nam suffered more severe pain than expected and will almost certainly not be able to return to the 2024 AFC U23 Championship.

The absence of Dinh Bac will be a big loss for U23 Vietnam at the 2024 AFC U23 Championship as this player is one of the most experienced players on the team despite being only 20 years old.

Dinh Bac's injury comes at a difficult time in the striker's career. Before participating in the 2024 AFC U23 Championship, Dinh Bac did not regularly play in the V-League due to non-professional issues.

In addition to Dinh Bac's absence, U23 Vietnam will also be without central defender Ngoc Thang in the next two matches due to suspension. In addition, striker Quoc Viet has physical problems and is also uncertain about playing against Malaysia.
