LONDON — Yu Yang, one of the Chinese badminton players disqualified from the Olympics, says she is quitting the sport.

Yang and her partner Xiaoli Wang were disqualified by the Badminton World Federation on Wednesday for “not using one’s best efforts to win a match”.

Two pairs from South Korea and one from Indonesia were also disqualified for making errors in Tuesday’s matches.

“This is my last time competing. Goodbye beloved badminton,” Yang said on her Twitter-like Weibo account.
