Real Madrid star striker Cristiano Ronaldo has said that the decision by Spain's administrative sports court to uphold his five-game ban for pushing a referee is "incomprehensible".
Ronaldo was suspended for one match after being sent off during the first leg of the Spanish Super Cup. Spanish media reports said Madrid appealed Ronaldo's second yellow card, when the Portugal forward was booked for diving.
Ronaldo was given an additional four-match ban for shoving the referee in the back after he was shown the red card.
"One more incomprehensible decision. From injustice to injustice, they will never overthrow me," Ronaldo said on Instagram.
"And as always I will come back stronger. Thank you to all who have supported me," he added.
Real won the Supercopa 5-1 on aggregate against Barcelona and opened their league season with a 3-0 win at Deportivo La Coruna in Ronaldo's absence on Saturday.
The Portuguese will not return to domestic action until September 20 against Real Betis, but can play in the Champions League.
Madrid coach Zinedine Zidane has also criticized the extended ban of his best player.
