Barcelona midfielder Cesc Fabregas has been ruled out for up to a month with a thigh injury.
The 25-year-old was forced off in the early stages of Sunday's 2-1 win at Real Betis in La Liga.
"FC Barcelona's Medical Services have confirmed that Cesc Fabregas has torn the bicep femoris in his left thigh," read a club statement.
"He'll be sidelined for three to four weeks."
The Catalan side restored their six-point lead at the top of the table with Sunday's victory at the Estadio Benito Villamarin.
