Liverpool have confirmed Torres will be out for "between 10 and 15 days" after a scan on his right hamstring on Thursday.
Torres was already expected to miss Saturday's Barclays Premier League match against Wigan, next week's trip to face Atletico Madrid in the Champions League and the following Sunday's crunch fixture at Chelsea.
And a scan on Thursday has confirmed he will be out for at least 10 days after doctors detected a tear in his right hamstring suffered in Spain's World Cup qualifier in Belgium last night.
Reds spokesman Ian Cotton said: "A scan on Fernando Torres has shown a tear in his right hamstring which will sideline the player for between 10 and 15 days.
"Ryan Babel has sprained his left ankle and is a major doubt for Wigan on Saturday."
