Liverpool have suffered yet another blow to their defence after Trent Alexander-Arnold was ruled out for a month with a knee injury.
Alexander-Arnold played the full 90 minutes on Saturday of Liverpool's 1-0 win at Brighton, however scans this week have revealed minor ligament damage.
It means he could face up to four weeks on the sidelines, and leaves the Premier League leaders even more threadbare when it comes to defensive reinforcements.
Alexander-Arnold has played in 22 matches for Liverpool this season, including 17 Premier League starts, scoring once and claiming three assists.
He joins Joe Gomez on the sidelines, with the fellow England international unlikely to return until February. Joel Matip has also been out, but has recently returned to full training.
A further blow for Jurgen Klopp is that Alexander-Arnold's obvious replacement at right back, Nathaniel Clyne, has been loaned to Bournemouth for the rest of the season.
Alexander-Arnold will miss at least four games, with the Premier League fixtures against Crystal Palace, Leicester, West Ham United and Bournemouth unlikely to feature the 20-year-old.
However there is hope that Alexander-Arnold will be fit to return for the Champions League last-16 clash against Bayern Munich.
Liverpool also face injury concerns in midfield, with Georginio Wijnaldum also struggling with a knee problem after the victory at the Amex Stadium.
Wijnaldum will miss Saturday's game against Palace, although he is not expected to be a long-term absentee.
