Sergio Busquets has been left out of Barcelona's 19-man squad to face Bayern Munich on Wednesday evening.
The Blaugrana host the Bundesliga champions looking to overturn a 4-0 deficit from the semi-final first leg last week.
But Tito Vilanova will have to do it without his midfield stalwart, who misses the clash due to injury.
Eric Abidal has also not been named due to a sore calf, whilst Javier Mascherano and Carles Puyol have not recovered in time from their ongoing injuries.
Barcelona squad to face Bayern Munich: Valdés, Pinto, Dani Alves, Piqué, Fàbregas, Xavi, Villa, Iniesta, Alexis, Messi, Thiago, Dos Santos, Bartra, Pedro, Montoya, Adriano, Song, Tello, Sergi Roberto
