Liverpool's Premier League title push suffered a setback on Thursday when their Spanish international striker Fernando Torres was ruled out for up to three weeks with a hamstring strain.
Torres, who had only just returned to the side after five weeks out with a similar problem, picked up the injury in the 1-0 UEFA Champions League win over Marseille at Anfield on Wednesday. Defender Fabio Aurelio will be out for a fortnight after picking up a calf problem in the same game.
A club spokesman said: "Fernando has a strain in his right hamstring and will be out of action for between two and three weeks. Fabio has a calf strain in his left leg and will be out for two weeks."
