Liverpool defender Jose Enrique has successfully undergone knee surgery but will be out of action until February.
The Spaniard, 27, made his last start on 5 October in a 3-1 win over Crystal Palace before succumbing to injury.
He made a second-half appearance in the 4-0 win over Fulham on 9 November but the problem flared up again.
"Enrique is expected to return to full training at Melwood in around 10 weeks' time," the club said.
The left-back, a £6m signing from Newcastle in August 2011, has started only six Premier League games this season.
