The 28-year-old was red-carded for raising his hands to Carlos Gurpegui and clashing with Ander Iturraspe in Sunday's clash with Athletic Bilbao.
The Spanish FA (RFEF) has announced that it will meet to discuss a suitable punishment for Ronaldo on Feb. 5, the same day that los Blancos face city rival Atletico Madrid in the Copa del Rey.
The former Manchester United attacker was shown a straight red card following a clash with Carlos Gurpegui Ander Iturraspe during Sunday's 1-1 La Liga draw away to Athletic Bilbao.
Under the RFEF's disciplinary system, the ban could cover anything from one game to in excess of three should the offense be considered to have been an act of violent conduct.
Madrid's next three league matches come against Villarreal at the Bernabeu on Saturday, away to Getafe on Sunday, Feb. 16 and at home to Elche the following Saturday, although the RFEF could decide to include the second-leg of the Copa semifinal clash with Atletico as part of any ban enforced upon Ronaldo.
Blancos coach Carlo Ancelotti hit out at referee Miguel Ayza's decision to send his star man off after the match on Sunday, saying: "I was not close to it, but the pictures show that it was a bit exaggerated."
The 2013 Ballon d'Or winner, who turns 29 on the day of the disciplinary hearing, has scored 32 goals in 30 games for Madrid this season.
