The right back was shown a yellow card in the 90th minute for time wasting when taking a throw in, his third booking of the group stage which means he is banned for the final group game at home to Borussia Dortmund on Dec. 6.
The yellow card meant holders Madrid, already guaranteed to finish second behind Tottenham Hotspur and progress to the last 16, would have Carvajal available for the knockout rounds of the competition without any yellow cards hanging over him.
UEFA's Control, Ethics and Disciplinary body will deal with the case on Dec. 7 and could suspend Spaniard Carvajal for an additional two matches.
