Real Madrid's appeal to reduce Cristiano Ronaldo's five-game ban was rejected by a Spanish government's tribunal on Tuesday.
Ronaldo was suspended after pushing referee Ricardo De Burgos Bengoetxea after being shown a second yellow card late in the first leg of the Spanish Super Cup.
Madrid had already had an initial appeal rejected by Spain's football federation (RFEF), as the sending off ruled him out of the Super Cup second leg, and a fresh appeal to the Tribunal Administrativo del Deporte to limit the additional four-game ban has now also been turned down.
There are no more avenues within Spain to which Real Madrid can appeal.
Ronaldo had called the punishment "over the top and ridiculous" and "persecution," and the superstar again hit out on social media on Tuesday after the latest appeal failed.

"Another incomprehensible decision," he wrote on Twitter. "Injustices that will never bring me down. And like always I will return even stronger. Thanks to those who have supported me."
Ronaldo already missed Madrid's first La Liga game against Deportivo La Coruna last weekend, and is now set to also sit out the next three games against Valencia, Levante and Real Sociedad.
He can return against Real Betis on Sept. 20.
Ronaldo was found guilty of violating Article 96 of the Disciplinary Code, which relates to using "mild force" against the officials, including grabbing, pushing or shaking. He was also fined €3,805, with Real fined €1,750.
Although the RFEF's disciplinary code is clear in saying that any slight push on a match official automatically brings a ban of between four and 12 matches, coach Zinedine Zidane said last week that "five games for what happened is a lot."
Fans and pundits have also expressed their frustration, claiming that Ronaldo's second yellow card was unmerited as there was contact with Barcelona defender Samuel Umtiti when he fell to the ground.
It was the sixth red card of Ronaldo's eight years at Madrid, and in previous cases the club have often pushed the appeals process as far as possible.
