Barcelona have confirmed left-back Adriano will miss up to six weeks with a hamstring injury.
The Brazil international was replaced by Dani Alves in the 23rd minute of their La Liga clash with Rayo Vallecano, after injuring himself by diving to connect with a pass from team-mate Andres Iniesta.
Barcelona subsequently confirmed the defender will spend a period on the sidelines, via its official Twitter account.
“Adriano suffered a hamstring tear in his right thigh. (The) approximate time out (will be) between four and six weeks,” read a post from Barcelona’s account.
Barca went on to win the home clash against Rayo 3-1 thanks to a David Villa strike and two goals either side of half-time from Lionel Messi.
Adriano, 28, looks set to miss both legs of his side’s Champions League tie with Paris Saint-Germain, as well as league meetings with Celta Vigo, Mallorca and Real Zaragoza.
