Barcelona will be without the services of Rafinha in the second leg of their Champions League quarter-final tie with Atletico Madrid due to an adductor strain.
The Brazil international recently made his comeback after a seven-month spell on the sidelines due to an anterior cruciate ligament injury - playing 26 minutes in Barca's 2-1 first-leg win over Atletico last week, before starting in Saturday's 1-0 Liga loss at Real Sociedad.
He made way for Andres Iniesta at half-time, though, and Barcelona have now announced Rafinha has picked up thigh problem that will briefly keep him out of action again.
"First team player Rafael 'Rafinha' Alcantara has suffered a strain to his left adductor," a statement on Barcelona's official website read.
"His availability for upcoming matches will depend on the speed of his recovery."
The 23-year-old has made eight appearances in all competitions for Barcelona this campaign.
