The Reds will also be without defenders Mamadou Sakho and Glen Johnson.
Sakho had started in Liverpool’s last 16 matches and has established himself as a key player in Rodgers’s three-man defence.
Rodgers could play a back-three made up consisting of Kolo Toure, Martin Skrtel and Lovren.
Emre Can who has started in defence for the last 12 games could be moved into a central midfield role.
