Liverpool's Ibrahima Konate has been ruled out for up to three weeks with a hamstring injury following Sunday's 2-1 FA Cup defeat at Brighton.
He could also be a doubt for the Champions League last-16 first leg against Real Madrid on 21 February.
Liverpool are currently without Virgil van Dijk, Luis Diaz, Roberto Firmino and Diogo Jota.
Netherlands defender Van Dijk was ruled out for more than a month with a hamstring problem at the start of January.
The situation may stop defender Nat Phillips' potential deadline-day move, while centre-back Rhys Williams was recalled from a loan spell at Blackpool this month.
