Not the best of mornings for Olympic badminton.

A disciplinary hearing is set for Wednesday for eight female badminton players, including the reigning world champions from China. They're accused of trying to throw their Olympic matches to capture an easier matchup in later rounds.

Doubles players from China, South Korea and Indonesia were charged with violating a code of conduct — "not using one's best efforts to win a match." They're also accused of "conducting oneself in a manner that is clearly abusive or detrimental to the sport."

The badminton federation is declining comment. The doubles pairs were all due to compete in quarterfinals Wednesday afternoon. Spectators at London's Wembley Arena booed when they realized players were apparently deliberately trying to lose.

Chinese players were accused of starting a domino effect by deliberately losing a game on Tuesday. In badminton, teams play in a round-robin format, and aren't knocked out if they lose an early game. A loss can lead to an easier opponent in later games.
