Madrid - Spanish giants Real Madrid and Atletico Madrid could be banned from registering new players for a year for irregularities in the signing of minors, Spanish radio station Cadena SER reported on Wednesday.
Barcelona are currently banned from registering players after they were handed the same ban for similar reasons a year ago.
The Catalan giants unsuccessfully appealed that ruling to the Court of Arbitration for Sport (CAS), however, the appeal did delay the application of the ban until January which allowed them to sign seven players, including Luis Suarez last summer.
