Liverpool midfielder Steven Gerrard will be out for three weeks after the club confirmed he suffered a hamstring tear during Wednesday night's FA Cup defeat at Everton.
The 28-year-old limped off 16 minutes into the Reds' fourth-round replay at Goodison Park and is now a doubt for the club's next two Barclays Premier League against Portsmouth and Manchester City.
A club spokesman told Liverpoolfc.tv: "A scan has confirmed a tear in the hamstring of Steven's left leg. He will be out of action for about three weeks."
Gerrard may also miss the first leg of Liverpool's Champions League last-16 tie with Real Madrid, which is due to take place at the Bernabeu on February 25.
The news comes as a big disappointment for Liverpool manager Rafael Benitez, who has come under fire from fans and sections of the media for selling striker Robbie Keane to Tottenham on transfer deadline day for around £12million.
Benitez did not have time to bring in a replacement for the Republic of Ireland striker, and Gerrard's absence will further weaken the Spaniard's attacking options as Liverpool look to close the two-point gap on league leaders Manchester United, who have a game in hand.
The Liverpool captain will also miss England's international friendly against Spain next Wednesday.
