Thiago Silva will be suspended for Brazil's World Cup semi-final against Germany - and FIFA has also ruled out action by its disciplinary committee for the challenge by Colombia's Juan Zuniga which left Neymar with a serious injury.
Brazil's federation, the CBF, had appealed against Thiago's yellow card but FIFA's disciplinary committee refused to consider it - appeals against cautions are only permitted in exceptional circumstances.
A FIFA statement said: "The disciplinary committee... cannot consider the matter given the fact that there is no legal basis entitling it to grant such request."
The CBF had also pushed for action against Zuniga but this was rejected by FIFA's disciplinary committee who said the referee had seen the incident.
FIFA added: "After an analysis of the matter and the extensive submission and documentation received from the CBF, the chairman came to the conclusion that the FIFA disciplinary committee cannot consider this matter in light of the conditions outlined in the FIFA disciplinary code... to be able to intervene in such a situation."
