Alisson Becker will be sidelined for up to two weeks with a hamstring injury, according to Liverpool manager Jurgen Klopp, with the Brazilian goalkeeper likely to miss games against Wolves, Midtjylland and Fulham.
Alisson felt his hamstring during Liverpool's 1-1 draw with Brighton on Saturday and was replaced by 22-year-old Caoimhin Kelleher for Tuesday night's 1-0 win over Ajax in the Champions League.
Kelleher produced a fine performance, including a crucial reflex save to deny Klaas-Jan Huntelaar as Liverpool booked their place in the knockout rounds.
And Klopp provided an update on the extent of Alisson's injury, emphasising it was an injury and not a Covid-19 infection or isolation.
