Liverpool defender Martin Skrtel will discover in the next 24 hours how long he is expected to be out injured after a scan revealed posterior cruciate ligament damage in his right knee.
The 23-year-old Slovakia international was given oxygen and left the field on a stretcher during Liverpool's 3-2 win over Manchester City after he fell awkwardly on the edge of his own penalty area.
"Martin underwent a scan on Monday morning which showed damage to the posterior cruciate ligament in his right knee," club spokesman Ian Cotton told Liverpool's official website.
"He will see a specialist on Tuesday to assess the extent of the injury, and will then have an accurate idea of the timescales involved before he is back playing again."
Skrtel, who was signed by Rafael Benitez in January from Zenit St Petersburg, has forged a solid partnership with Jamie Carragher at the heart of a Liverpool defence, which has conceded only four goals in seven Barclays Premier League matches this season.
