Football news - Barcelona's Ousmane Dembele ruled out for six months and will miss Euro 2020

"First team player Ousmane Dembele has been operated on satisfactorily in Turku by Doctor Lasse Lempainen, (regarding) the rupture of the hamstring in his right leg," Barcelona said in a statement. "The approximate time out is six months."

The Spanish champions will be allowed to make an emergency signing to replace him provided the Spanish football federation (RFEF) ratifies Dembele's medical report.

RFEF rules dictate that if a player is out injured for at least five months then their club can sign a replacement outside a transfer window, as long as they are based in Spain's top two divisions or they are a free agent.

The injured player is not allowed to play again for the team before the five-month period has elapsed and must agree to the arrival of the new player.

Barcelona have been linked to Real Sociedad forward Willian Jose by Spanish media.

This is Dembele's 10th injury since arriving from Borussia Dortmund in 2017 for 105 million euros ($115 million). The forward initially hurt his right hamstring playing against his former side in November.

Dembele missed five months of his debut season due to a hamstring problem in his left leg that required surgery and has made five starts in all competitions this season.

Barcelona are second in La Liga, three points behind rivals Real Madrid.
