LONDON (AP) — Eight female badminton players, including the world champions from China, face a disciplinary hearing Wednesday after being accused of trying to throw matches at the Olympics a day earlier to secure a favorable draw.

The Badminton World Federation said in a statement it had charged the doubles players from China, South Korea and Indonesia under its players’ code of conduct with “not using one’s best efforts to win a match” and “conducting oneself in a manner that is clearly abusive or detrimental to the sport.”
