Real Madrid pair Casemiro and Ferland Mendy are out of the second-leg of their Champions League round 16 tie with PSG.
Real lost the first-leg 1-0 in Paris on Tuesday night.
Casemiro was cautioned in the first half, meaning he will now have to sit out of the second leg against Paris Saint-Germain at the Estadio Santiago Bernabeu for a tackle he made on Leandro Paredes in midfield.
The tension between the two was clear as the Brazilian grabbed the Argentine by the throat. VAR did take a second look at the incident, but nothing more than a yellow card was deemed necessary. But the booking is costly for Carlo Ancelotti's second-leg plan.
With Casemiro's suspension already causing problems for Los Blancos, Ancelotti would have been left frustrated when Mendy picked up a yellow card of his own, meaning he too will miss out on the second leg in Madrid.
