Chelsea midfielder Michael Essien is available for the Blues in the English Premier League on Thursday after serving a one-match ban.
The Ghana international is available for selection for the match against Swansea after missing Monday's draw against Arsenal on Monday through suspension.
Essien was banned for the match against Arsenal after accumulating five yellow cards.
Chelsea boss Jose Mourinho is likely to rotate his options for the Boxing Day encounter with Swansea, meaning Essien could start in central midfield.
Ashley Cole could start at left-back.
With the Blues facing Premier League leaders Liverpool on Sunday, Mourinho may opt to withdraw the likes of captain John Terry, who has played every league game this season, from the first line of battle.
Provisional squad: Cech, Ivanovic, Cole, Luiz, Essien, Ramires, Lampard, Torres, Mata, Oscar, Mikel, Schurrle, De Bruyne, Hazard, Ba, Willian, Schwarzer, Cahill, Terry, Azpilicueta, Eto'o, Blackman, Bertrand.
