Real Madrid remain expelled from the Copa del Rey after Spain's Court of Arbitration for Sport (CAS) upheld a second appeal by the club to be reinstated.
Los Blancos were kicked out of the cup competition for fielding an ineligible player, after Denis Cheryshev featured in the last-32 first-leg clash against Cadiz, despite being suspended.
Rafael Benitez's side went on to win the match 3-1 with Cheryshev giving them the lead after just three minutes. However, the Russian winger was supposed to be serving a ban after he picked up three bookings during a loan spell at Villarreal in last season's edition.
Real initially contested the punishment meted out by the Spanish football federation (RFEF), which was rejected by their appeals committee on Thursday, and they received the same judgment from CAS the following day.
A court official told The Associated Press: "Madrid remain penalized, they are still disqualified."
A statement added: "The court, which studied all the arguments in the case as well as the documentation received in the federation, has agreed that we will not concede the appeal sought by the club because they did not meet the requirements of the current rules. This does not imply a detailed analysis of the appeal."
CAS president Enrique Arnaldo said that the La Liga club "must first request a report from the agency that emitted the decision as well as supply us with a copy of the entire administrative file with all information properly included."
