Real Madrid may appeal against the yellow card collected by David Beckham against Athletic Bilbao on Sunday.
The booking was Beckham’s 10th of the season and means he will miss Real’s game with title rivals Sevilla on Sunday.
“If it is possible to appeal against it, we will do it,” sporting director Predrag Mijatovic told Real’s website.
If Beckham misses the match, he would only have five games left for Real before moving to LA Galaxy.
Real coach Fabio Capello said: “I don’t want to talk about Beckham’s card, nor anything to do with the referees.
“His absence would be a very big loss. Now he is in very good form and against Athletic he had a great game.”
Real are currently third in La Liga table, a point behind second-placed Sevilla and two points behind leaders Barcelona, with six games remaining.
