Jugones, the sports news bulletin in the Spanish TV station La Sexta, were the first mainstream media to report the news:

Consideran que Luis Suárez NO PODRÍA JUGAR el Clásico. ¿POR QUÉ? Lo vemos en #Jugones http://t.co/iYVyWvucyZ — JugoneslaSexta (@JugoneslaSexta) octubre 21, 2014





They spoke to a member of Deporte de Ley, a Spanish website created by attorneys specialized on sports law, regarding an article they published in which they claim that Luis Suárez should not play El Clásico next Saturday. According to them, Suárez's ban does not end on October 24th, as Barcelona stated, but on October 25th, the day when the Clásico will be held. The reasons they provide to support their claim are the following:

According to the resolution published by the CAS, Luis Suárez is banned to take part in any official match for four months, starting on June 25th.

The bans whose length is specified in months are computed "from date to date", i.e., if it started the 25th day of certain month, it has to end the 25th of another month, but it will definitely be valid that day.

As a result, they claim that Suárez's ban will still be valid on October 25th and, therefore, he would not be allowed to play El Clásico. In fact, if he were to play, FC Barcelona could be punished for an incorrect lineup and this could result in them losing the game automatically.
