Striker Fernando Torres has been ruled out of Liverpool's remaining games of the season following more knee surgery.
The Spain striker was sidelined for a month in January following a knee operation and has now been told that he faces a further six weeks on the sidelines after going under the knife to repair a torn cartilage.
That means Torres will miss the Reds' final games of the Premier League season and also the club's Europa League run-in, which resumes this week with a semi-final clash with the striker's former club Atletico Madrid.
The 26-year-old missed last weekend's goalless draw against Fulham and his absence during the closing weeks of the season will be a major blow to manager Rafael Benitez's hopes of finishing in the European qualifying places.
A spokesman told the club's official website:"Fernando saw a specialist in Spain earlier today and it was decided that he would need surgery on a torn cartilage in his right knee.
"This will be carried out later tonight.
"We cannot comment ahead of the operation, but as a guide, the usual rehabilitation period for this type of procedure is around six weeks."
Torres is also now facing a race against time to be fit for this summer's World Cup.
Spain coach Vicente del Bosque will be keeping his fingers crossed that the striker can prove his fitness ahead of the deadline for naming his final 23-man squad on June 16.
