Tests performed this Monday morning on Sergi Roberto have revealed that he has indeed injured his left hamstring, specifically the biceps femoral muscle in the thigh. He will be unavailable for selection until he has recovered from the problem.
After starting Sunday's 0-0 draw with Getafe, he had to leave the field after 15 minutes following an isolated incident. Sergi Roberto has made 30 appearances this season, 20 of those in La Liga, scoring 4 goals and giving 3 assists.
