Real Madrid boss Zinedine Zidane has suggested that Eden Hazard suffered a sprained ankle during the 2-2 draw with Paris Saint-Germain on Tuesday night.
After producing arguably his best performance in a Los Blancos shirt, Hazard needed to be substituted after sustaining an ankle injury courtesy of a challenge from Thomas Meunier.
While Real are yet to officially reveal the extent of the problem, Zidane has admitted that he is 'a little worried' about the issue.
The Frenchman is quoted by The Mirror as saying: "There is a little worry over Hazard at full time. He was in pain at full time, and we think it is more than an impact injury.
"It is a sprained ankle, but hopefully not a severe sprain. We will know more in the coming days."
Real will hope to have Hazard available for the El Clasico showdown with Barcelona on December 18.
