Real Madrid star Cristiano Ronaldo has collected an ankle knock.
Ronaldo completed 90 minutes as Real Madrid slumped to an astonishing 5-0 defeat away to fierce rivals Barcelona on Monday.
But the Portugal international was unable to join his team-mates for training on Wednesday due to injury and Real are now sweating on his fitness ahead of this weekend's game against Valencia.
The extent of the damage will become clearer before kick-off on Saturday and Real will be hoping he is not facing a spell on the sidelines.
"Cristiano Ronaldo was subjected to a medical check before training," read a club statement.
"Results show an inflamed tendon on his right ankle. The player will follow a medical treatment and have physiotherapy, and will be monitored for the next 24-48 hours."
