Sergio Ramos will undergo tests in the next few days after the defender picked up a potential injury during Real Madrid’s 3-1 win against Napoli.
Ramos collided with Jose Callejon in the early stages of Wednesday’s clash at the Santiago Bernabeu, before being substituted with 20 minutes remaining.
Zinedine Zidane maintained after the game that the centre-back was ultimately taken off due to his yellow card but conceded he had a “knock”.
Marca reports Ramos will be examined before the weekend to see if he can play against Espanyol or whether he has sustained something more serious.
