Brazil has asked FIFA to overturn captain Thiago's Silva's yellow card from Friday's match against Colombia. It was Silva's second card of the tournament, therefore he's currently suspended for Tuesday's semifinal match against Germany.
FIFA has acknowledged that a complaint has been lodged, according to ESPNFC.com.
"I can confirm we have received an appeal from the CBF [Brazil's soccer organization] and this is being analyzed," FIFA's head of media relations Delia Fischer said.
Silva was booked in the 64th minute of Friday's match when he impeded a kick from Colombia keeper David Ospina. There is little precedent for such a decision, and, in short, it is highly unlikely the call be overturned. Beyond that, a move by FIFA to re-admit one of Brazil's best players would be extremely controversial.
Silva scored Brazil's first goal Friday when he found himself alone on the far post of a corner kick. It is his only goal of the tournament, but Silva's worth is far beyond anything he provides offensively for the Brazilians.
With superstar Neymar sidelined, the loss of Silva will only further cripple an already damaged Brazil side.
