Barcelona have offered an injury update on Pau Cubarsi after the defender returned to the club from international duty with Spain.
Cubarsi picked up an ankle injury during the 2-2 draw with the Netherlands and was taken off in the first half.
Spain boss Luis de la Fuente said he was hopeful Cubarsi could play in the return leg on Sunday but he was subsequently sent back to his club.
Barcelona have now conducted further tests and issued a diagnosis.
“The tests conducted this morning at the Ciutat Esportiva Joan Gamper have shown that first-team player Pau Cubarsí has an elongation of the anterior tibiofibular ligament in his right ankle.
