Lucas Leiva is facing up to six weeks on the sidelines, Jurgen Klopp revealed on Friday afternoon.
The Brazilian midfielder picked up a thigh problem while taking a penalty in Sunday’s League Cup final defeat against Manchester City.
Lucas suffered the double agony of having his spot-kick saved by Willy Caballero and sustaining an injury that will keep him out until mid-April.
The midfield anchorman, who impressed as a makeshift centre-back in the League Cup final, is out of the Europa League double-header against Manchester United as well as six Premier League matches, against Crystal Palace, Chelsea, Southampton, Tottenham, Stoke and Bournemouth.
Speaking at his media briefing on Friday, Klopp said: “No Lucas, it is really unfortunate and a little bit more serious as I’ve never heard of an injury like this with a penalty. It is his quad. I don’t know exactly but he’ll be out for five to six weeks.”
In other Liverpool injury news, Mamadou Sakho has returned to training after missing the 3-0 midweek win against City as Liverpool avenged their loss.
Daniel Sturridge also took part in the session on Friday and is in contention to return to the side to face Crystal Palace.
Martin Skrtel could also make his first appearance in almost three months.
