"The player has been diagnosed with a muscular injury in the biceps femoris of his left leg. His progress will be monitored," Real Madrid said in a statement without revealing the length of his absence.

According to Spanish press reports Camavinga, who already injured his knee last September, is expected to be sidelined for between two and three weeks.

The 22-year-old came off in the 56th minute with the same injury which has kept teammate Vinicius Junior out of action for several weeks.

Madrid have various players out injured for long periods, including Dani Carvajal and Eder Militao with severe knee injuries.

According to several Spanish media reports Kylian Mbappe, Jude Bellingham and Brahim Diaz also finished the match in pain and will undergo medical tests on Friday.

Champions League holders Real have lost three of their five matches and with six points they are currently 24th, the very last qualifying spot for the knockout phase.
