LONDON (AP) ― The format of Olympic badminton will be reviewed to avoid a repeat of the match-throwing scandal that blighted the London Games, but the governing body of the sport said Sunday no changes were guaranteed.

Thomas Lund, general secretary of the Badminton World Federation, said a full tournament evaluation will be presented at a federation meeting in November, including a report on the debut of group play in London.

Four women’s doubles pairs ― the gold medal favorites from China, plus two from South Korea and one from Indonesia ― took advantage of the format by trying to lose group matches to give themselves easier quarterfinal matchups. They were disqualified.

Lund said the federation regarded the group system, in which teams play a set of games before a knockout tournament, as “a big success” compared with having only a tournament.

“It has brought action to many, many more viewers and prolonged the Olympic experience for many, many more players,” he said.
