FIFA have yet to receive a formal complaint from the Brazilian confederation regarding Kaka's sending-off against Ivory Coast on Sunday night.
The Real Madrid star was dismissed by French referee Stephane Lannoy for what he deemed to be two bookable offences, the second of which was a collision with Ivory Coast's Kader Keita who appeared to make a meal of the contact.
Under Article 72 of FIFA's disciplinary code it is almost certain that any appeal from the Brazilians on Kaka's behalf would fail, because the referee's decision is considered final except in circumstances where he has clearly booked the wrong player.
There had earlier been controversy over Luis Fabiano's second goal for Brazil in the 3-1 win, as he appeared twice to handle the ball before firing it in. Again, FIFA were not aware of any formal complaint at this stage from the Ivorians.
FIFA head of media Nicolas Maingot said: "I am not aware of any complaints from the two teams. If this is the case we will analyse the request and respond to it."
