Barcelona forward Neymar will be unavailable for El Clasico with La Liga leaders Real Madrid on April 23 due to a three-match suspension from the Royal Spanish Football Federation (RFEF).
Barca was trailing 1-0 in its meeting with Malaga on Saturday when Neymar was shown a second yellow card for a poor challengeon Diego Llorente.
The Brazilian would typically have received a one-match ban for the dismissal but due to his alleged sarcasticapplause forthe fourth official when he left the pitch, he has been punished further.
Barca told the RFEF's competition committee that it could not be proved that Neymar had directed his reaction to the fourth official as he made his way from the field.
The committee rejected this claim on the grounds that Barca provided no evidence to back up their version of events, meaning Neymar must sit out the matches against Real Sociedad, Madrid and Osasuna.
The 25-year-old will return for the derby match with Espanyol on April 29. However, Barca does have an option to appeal the sanction.
Teammate Javier Mascherano told a news conference on Monday:"There have been other players who have done the same and have only received one-game suspensions. We'll see.
"It is very easy to talk from the sofa at home and very difficult to make decisions in high intensity. Sometimes you are wrong, it has happened to me, and there is nothing left to learn from the error.
"We are not going to point blame between us. When someone is wrong or gets into trouble, we tend to try to help him."
Luis Enrique's side was unable to find a route back into the match and fell 2-0 at Malaga, dealing its title challenge a major blow with rivals Madrid three points clear and possessinga game in hand.
Barca will already be without long-term absentees Aleix Vidal and Rafinha when it heads to the Santiago Bernabeu, while Arda Turan's fitness continues to be monitored.
