On Monday evening, Duan offered a public apology, saying he should have obeyed the referee's decisions unconditionally, Xinhua reported.
"As the culprit, I have brought Chinese football into disrepute. I did wrong," he said in a statement posted on the Shenyang club's social media account.
Duan added that he recognizes the consequences of the matter and is ready to accept any punishment the Chinese Football Association impose on him.
