Virgil van Dijk has undergone “successful” knee surgery to repair the anterior cruciate ligament damage he sustained in the Merseyside derby, Liverpool confirmed.
The Dutch centre-back suffered the injury in a challenge with Everton goalkeeper Jordan Pickford during the 2-2 draw at Goodison Park on October 17.
“The Liverpool defender’s planned operation took place in London and was conducted successfully,”.
“Van Dijk will now immediately focus on the beginning of his rehabilitation with the support of the Reds’ medical department.
“No timeframe has been placed on the Dutchman’s return to action.”
Liverpool’s defensive worries worsened on Tuesday night when makeshift centre-back Fabinho suffered a suspected hamstring injury in their 2-0 win over Midtjylland in the Champions League.
Fabinho, who had previously filled in for Van Dijk for the wins over Ajax and Sheffield United, was forced off after half an hour at Anfield.
