Real included Denis Cheryshev in their starting lineup for last week's last 32, first leg game at third-tier Cadiz even though he should have been serving a one-match suspension. The Russia forward opened the scoring in a 3-1 victory.
Real president Florentino Perez insisted the club had not broken the rules and said neither Cheryshev, who incurred the sanction playing on loan at Villarreal last season, nor Real were notified that he was banned.
However, the RFEF sharply criticised Real in an initial nine-page ruling, saying they should have been aware of the ban, and as well as disqualifying the club fined them 6,001 euros ($6,571.10).
The federation's appeals committee rejected Real's plea, meaning the club is likely to lodge a new appeal with the Spanish government's Disciplinary Committee for Sports (TAD), which typically meets every Friday.
The Cup return leg was due to be played at Real's Bernabeu stadium next Wednesday.
Former Real midfielder Figo had little sympathy for Cheryshev when asked about the issue at an event in Madrid on Thursday.
“If I was ever banned I knew about it and I knew that I could not play,” the Portugal great said. – Reuters
