Harvey Elliott has returned to light training after he dislocated his ankle against Leeds in September.
The 18-year-old has been running on grass for the first time on Monday since dislocating the joint in a tackle from Pascal Struijk, who was subsequently sent off.
Elliott completed exercises outside and in the gym at Liverpool's Kirkby training ground, just two months after undergoing surgery to repair the damage.
It brought the youngster's excellent start to the season to an abrupt halt. Elliott is the Premier League's youngest debutant, following his transfer from Fulham as a 16-year-old.
He had started all of Liverpool's opening four Premier League games after an impressive pre-season and season-long loan at Blackburn during 2020-21.
Liverpool were also assessing Jordan Henderson on Monday after he sustained a knock for England and withdrew from the squad, while Sadio Mane will also be looked at by Liverpool medical staff this week.
Mane was forced out of international duty with Senegal after a heavy collision during a fixture against Togo over the weekend, although manager Aliou Cisse reportedly played down the significance of the injury.
Manager Jurgen Klopp will hope both are available for Saturday's Premier League clash with Arsenal and the subsequent Champions League group game against Porto, after his side were beaten at West Ham last time out.
