Liverpool boss Jurgen Klopp admits they face a longer wait to see Jordan Henderson and Alberto Moreno back from injury.
The pair will sit out the Reds' Anfield clash with Leicester City on December 30 as well as the trip to Burnley on New Year's Day.
Klopp told his post-Swansea press conference: “Length of time [on their returns], actually I have no idea to be honest – but it won't be tomorrow. Both are out for the next two games for sure.
“On December 30 and January 1, they have no chance, then we have to see again."
