Senegal have appealed against the decision by Caf to ban defender Souleymane Diawara for two matches.
The France-based player was handed the ban after being cautioned in an African Cup of Nations qualifier against Cameroon in June.
Diawara is among four players banned by the disciplinary committee of Caf for accumulation of yellow cards.
Striker Mamadou Niang, midfielder Lamine Sane and coach Amara Traore were each banned for one match.
Issiar Dia and Diawara received two-match suspensions following a report sent to the continent's governing body after the Teranga Lions won the goalless drawn game in Yaounde.
In his report to Caf, Angolan referee Helder Carvalho said he booked four Senegal players in the temperamental match.
Coach Traore was dismissed for contesting the referee's decisions.
But the Senegal Football Federation (SFF) insists the referee erred by claiming in his match report that he cautioned Diawara during the game.
"The SFF has received a letter from Caf notifying us of a two-match ban imposed by Caf following the match in Yaounde," the SFF said in a statement.
"The SFF has sent an appeal to Caf together with picture evidence to draw their attention to a mistake by the referee. He did not caution Diawara at any point in the game."
Senegal lead Group E with 10 points and will qualify for the Africa Cup of Nations if they beat second-placed DR Congo in their next game in September.
