Burkina Faso has appealed the sending-off of midfielder Jonathan Pitroipa in the semi-final victory over Ghana.
Burkina Faso reached Sunday's final of the Africa Cup of Nations for the first time after a 3-2 penalty shootout win.
The west African country, with a population of just under 16 million and their capital city of Ouagadougou, will play 1994 winners Nigeria in Johannesburg but they desperately want Pitroipa to play.
Burkina Faso's director Gualbert Kabore said a complaint has been lodged with CAF over the red card by referee Slim Jedidi after the match.
The 26-year-old former Hamburg player was shown a second yellow card for simulation by the Tunisian referee after he fell in the Ghanaian penalty area despite strong appeals for a penalty.
"We lodged an appeal immediately after the match," Kabore said.
"Our FA's secretary general sent a fax to CAFwithin two hours after the game according to the regulations.
"The referee's decision was outrageous. We are confident of a favourable outcome and Pitroipa would be able to play the final.
"We will fight and do everything within the rules and regulations to bring justice."
