Chile head to CAS in bid to have Ecuador thrown out of Qatar World Cup
Chile would appeal to the CAS as the 'weight of evidence is clear'.
FIFA's appeals committee have rejected a bid to have Ecuador thrown out of the World Cup - though Chile have vowed to appeal the decision.
Football's governing body dismissed Chile's argument that Byron Castillo is actually Colombian and ineligible to play in Ecuador's World Cup qualifying games.
Sportsmail had previously revealed evidence by publishing an audio recording of Ecuador international Castillo revealing birth details which matched his Colombian birth certificate earlier this week.
However, Friday's decision means Ecuador are still going to play at the World Cup in Qatar later this year.
However, rivals Chile - who had hoped to take their place - have insisted they will take the matter to the Court of Arbitration for Sport.
A statement from the general secretary of the Chilean Football Federation, Jorge Yunge, described the decision as a 'dark day for football'.
FIFA's statement concluded that Castillo is considered to hold permanent Ecuadorian nationality and they confirmed they have closed the proceedings.
The verdict, which upholds a FIFA disciplinary ruling from June, keeps Ecuador on track to play Qatar in the opening game of the World Cup in Doha on 20 November. The Netherlands and Senegal are also in Group A.
FIFA's statement on Friday afternoon read: 'Having analysed the submissions of all parties and after a hearing had been conducted, the Appeal Committee confirmed the decision of the Disciplinary Committee to close the proceedings initiated against the FEF (Ecuador Football Association).
'Amongst other considerations, it deemed that on the basis of the documents presented, the player was to be considered as holding permanent Ecuadorian nationality in accordance with art. 5 par. 1 of the FIFA Regulations Governing the Application of the Statutes.
Yunge though said Chile would appeal to the CAS as the 'weight of evidence is clear'.
He said: 'This is a dark day for football and for the credibility of the system. The footballing world heard a player who helped Ecuador qualify for the FIFA World Cup admit he was born in Colombia and that he gained an Ecuadorian passport using false information.
'No wonder he refused to participate in the FIFA hearing. What does it say about Appeal Committee that confronted with all this still they fail to act?
'Of course, we will refer this to the Court of Arbitration for Sport because the weight of evidence is clear and we urge the Appeal Committee to deliver the grounds of the decision very quickly because there were enough unjustifiable delays and postponements in this case.'
Chile's hopes of securing a last-minute ticket to the World Cup in extraordinary circumstances were thought to have been given a boost when Castillo failed to attend the FIFA Appeal Commission hearing into his nationality.
