Equatorial Guinea, making their debut at the Women's World Cup, have dropped two of their star players - Salimata and Bilguisa Simpore - ahead of the tournament.
The sisters were key players for the Guinean side at the 2010 African Women's Championship in South Africa, but were hit by controversy after they were accused of being men by members of the Ghana side. Salimata was also accused of having played for both Burkina Faso and Ivory Coast before.
Black Queens' captain Florence Okoe said at the time: "It is not as if we are throwing sour grapes, just because we have lost. Rather, this is the fact and it is up to the organisers to do something about this. It is not good for African women's football.''
Ghana team-mate Diana Ankomah added: ''You only need to have physical contact with them to know this, and we can tell from what happened most times during the match."
The allegations have never been proven and CAF have refused to comment on the matter, but question marks remain over the pair's withdrawal from the tournament.
