Vinicius Junior looks set to miss Real Madrid's Champions League clash with Liverpool after sustaining a hamstring injury.
The Brazil forward played the whole match on Sunday as Real won 3-0 at Leganes in LaLiga but now appears to be facing a spell on the sidelines.
A statement from the club on Monday said: "Following tests carried out today by the Real Madrid medical services on our player Vini Jr, he has been diagnosed with an injury to the biceps femoris in his left leg. His progress will be monitored."
Real did not announce how long Vinicius is likely to be out for but reports in the Spanish press suggest the 24-year-old will be sidelined for almost a month.
