Alisson Becker has sustained a hamstring injury and is not expected to return until after the next international break in November.
This means Liverpool will be without their No 1 goalkeeper until November.
He is expected to miss matches against Chelsea, Arsenal, Brighton, and Aston Villa in the Premier League, as well as two Champions League fixtures against RB Leipzig and Bayer Leverkusen.
Liverpool also face Brighton in the Carabao Cup, but Caoimhin Kelleher featured in the last round.
He was substituted in the second half of Liverpool’s 1-0 win over Crystal Palace at Selhurst Park on Saturday. With regular No 2 Kelleher unavailable through illness, 23-year-old Vítezslav Jaros made his Premier League debut, keeping a clean sheet.
