Ousmane Dembele will miss the first Clasico of the season after being handed a two-match ban by the Royal Spanish Football Federation (RFEF).
The Barcelona winger was sent off in the closing minutes of the 4-0 LaLiga win over Sevilla last Sunday after confronting referee Antonio Miguel Mateu Lahoz, who had just given debutant Ronald Araujo a red card for a foul on Javier Hernandez.
According to the referee's match report, Dembele said to him, "Very bad, you are very bad", as Barca players surrounded him to argue against Araujo's dismissal.
Barca appealed against Dembele's red card but the RFEF has dismissed their case and given the France international a two-game ban.
He will therefore sit out the trip to Eibar on October 19 and then the visit of Real Madrid to Camp Nou on October 26.
Araujo has been banned for one game, as has Gerard Pique, who has collected five bookings this season. Both will be available to face Madrid.
Dembele has made three LaLiga appearances this season and scored his first goal of 2019-20 in the defeat of Sevilla.
Barca are two points behind league leaders Real Madrid after eight matches.
