London, Dec 2 (IANS) Liverpool midfielder Lucas Leiva is out for the rest of the season after suffering a knee injury, the English Premier League club has confirmed.

Liverpool confirmed Thursday that the Brazil international had an injury to the anterior cruciate ligament in his left knee.

‘Lucas will undergo surgery and unfortunately be ruled out for the remainder of the current campaign,’ the club said on its official website.

The 24-year-old Lucas, injured in a clash with Chelsea’s Juan Mata, has been one of Liverpool’s best players for the past two seasons.

And he has been in fine form during the past fortnight, starring in Liverpool’s Premier League and League Cup wins over Chelsea and Sunday’s 1-1 league draw with leaders Manchester City.
