He is likely to be replaced by Martin Skrtel, who was dropped to the bench at the weekend to allow for the return of Daniel Agger after a month out injured.
Liverpool's only other absentees are striker Fernando Torres (knee), Yossi Benayoun (rib) and Glen Johnson (knee), all of whom are still some way off full fitness.
Provisional squad: Reina, Skrtel, Agger, Carragher, Insua, Gerrard, Lucas, Rodriguez, Riera, Ngog, Kuyt, Cavalieri, Pacheco, Spearing, Darby, Babel, Aurelio, Degen.
