Real Madrid goalkeeper Thibaut Courtois is reportedly suffering from sciatica and it is not yet known when he will return to action.
Courtois missed Real Madrid's La Liga match against Osasuna on Sunday due to a sciatica attack.
Ansah revealed, "He had to be examined on Monday and I think it was his sciatic nerve problem."
The Belgian goalkeeper is reportedly undergoing treatment at Real Madrid Sporting City, but doctors are unsure when his pain will go away.
The source said, "It could take a few days, or it could take a few weeks."
If Courtois is unable to play, it will be substitute goalkeeper Luing who will start Wednesday's home game against Donetsk Miners. And the good news for Real Madrid is that Modric returned to training on Monday and is available for the Champions League match after missing the last game due to injury.
