FIFA says Japan women's soccer coach Norio Sasaki won't be disciplined for instructing his players to avoid winning a match at the London Olympics.

The decision came as four teams in women's badminton were disqualified from the Olympics for deliberately losing group matches to manipulate their quarterfinal opponents.

Sasaki said in a news conference after Tuesday's 0-0 draw with South Africa that he did not want his team to travel to Scotland for a quarterfinal on Friday.

The result meant Japan stayed in Cardiff, Wales, and will play Brazil on Friday instead.

FIFA says its disciplinary committee studied Sasaki's comments and "there are no sufficient elements to start disciplinary proceedings" for corruption or "unlawfully influencing match results."
