Liverpool could be without defender Joel Matip for a further six games because of confusion over availability.
Matip 'refused to play' for Cameroon after being named in the preliminary squad for the Africa Cup of Nations.
Matip who has made 14 appearances for the Reds this season, last played for Cameroon in September 2015.
Fifa says that without Cameroon's permission, Matip, 25, cannot play for the Reds until the end of their participation in the tournament.
Liverpool will take on Swansea in the Premier League at 12.30am Sunday.
