The Portuguese star was booked for diving against Rayo Vallecano, reaching his yellow cards limit.
In the 51st minute of the game at Vallecas on Wednesday night, match official Melero Lopes wasn't impressed with Cristiano Ronaldo, booking the Portuguese star for what he perceived to be a dive inside the penalty area. This was also the reason noted in the referee's post-match report.
However, via their official website, Real Madrid have issued a statement on Thursday announcing they have forwarded an appeal RFEF Competition Committee, with the aim of getting Ronaldo's yellow card rescinded.
Real Madrid believe there was contact made by Rayo Vallecano defender Antonio Amaya and will present video evidence as proof, to suggest the decision by the referee to yellow card Cristiano was incorrect.
The significance of this particular yellow card is that the 30-year-old has accumulated five bookings, therefore reaching the mandatory limit that is accompanied by a one-match suspension.
Should the appeal fall through and the yellow card not be rescinded, the 2014 FIFA Ballon d'Or winner will miss Saturday's La Liga encounter with Eibar at the Santiago Bernabeu.
If the appeal fails, it will leave manager Carlo Ancelotti forced to shuffle his team around, as midfielders Toni Kroos and James Rodríguez are likewise suspended for the match against the Basque minnows.
