Tuan Anh (14) has to leave the pitch after the first half.

Despite the absence of their creative midfielder in the second half, Vietnam managed to hold on to the 1-0 lead produced by midfielder Quang Hai’s brilliant goal in the 40th minute.

Tuan Anh wrote to fans on social media on Friday, “I’m OK. Thanks for your support!”

The doctors say Tuan Anh’s injury is minor but he still needs some time to recover. It’s possible that Tuan Anh may have to sit out next Tuesday’s match against Indonesia.
