Barcelona left-back Jordi Alba hobbled off in the 20th minute of the Spanish champions' La Liga game against Getafe on Saturday with an apparent right thigh injury.
The 30-year-old left the field wincing in pain and was replaced by Junior Firpo. It is the third injury for the Spain international this season, having spent two spells on the sidelines with injuries to his left thigh.
