Defender Martin Skrtel will miss Sunday’s Premier League visit of Blackburn after sustaining a suspected broken foot in last night’s Europa League victory over Unirea Urziceni in Bucharest.
The extent of the injury will be discovered after further examination at the club’s Melwood training ground but he has already been ruled out for this weekend.
His absence causes problems for manager Rafael Benitez as fellow centre-back Sotirios Kyrgiakos serves the final game of a three-match suspension.
Jamie Carragher is likely to revert to his usual role in the centre, meaning Philipp Degen or youngster Martin Kelly could come in at right-back as, although Glen Johnson is close to full fitness after a knee problem, he is not in contention yet.
Midfielder Maxi Rodriguez returns to the squad having been ineligible for the trip to Romania.
Provisional squad: Reina, Degen, Agger, Carragher, Insua, Gerrard, Lucas, Aquilani, Benayoun, Riera, Rodriguez, Ngog, Kuyt, Torres, Cavalieri, Pacheco, Spearing, Darby, Babel, Aurelio, Kelly.
