Barcelona defender Adriano has been ruled out for three weeks through injury.
Adriano suffered a tear in his right thigh after netting the opener in Barca's 3-1 win over Celta Vigo on Saturday.
And the 28-year-old joins Gerard Pique, Eric Abidal and Carles Puyol on the injury list, handing Tito Vilanova another blow to his already sparse back line.
A statement on the club's website read: "Adriano Correia sustained a tear in the adductor of his right thigh in the match against Celta.
"He'll be out of action for three weeks, according to the club's medical services."
Vilanova will have to shuffle the pack for his side's Champions League clash with Celtic on Wednesday, with Sergio Busquets also missing out through suspension.
Alex Song, Marc Batra and Javier Mascherano could feature for Barcelona, who sit top of La Liga after a club-record start of nine wins and a draw.
