London, England (Sports Network) - Disciplinary cases have been opened against four women's badminton doubles teams under accusations they threw matches the day before to improve their chances in the Olympic tournament.
The Badminton World Federation said it was holding a formal hearing Wednesday morning and would make a decision on what to do afterward.
World champions Wang Xiaoli and Yu Yan of China were among those being looked at after a loss to Jung Ke and Kim HN of South Korea on Tuesday in which the two teams appeared not to be trying to win the match.
Tournament referee Torsten Berg was called to the court after a series of serves into the net. The crowd booed, and Berg warned the players.
The loss guaranteed that Wang and Yu, the tournament's top seed, won't face countrywomen Tian Qing and Zhao Yunlei, the No. 2 team, until the gold medal final on Aug. 4.
Later, South Korea's Ha Jung Eun and Kim Min Jung and Indonesia's Greysia Polii and Meiliana Jauhari were warned about the play in their match by Berg, who brandished black sending-off cards threatening to expel the players, but never used them.
