Chelsea could change all 10 outfield players for the visit of Brendan Rodgers' Swans.
A youthful Blues side were taken to penalties in their midweek Carling Cup third-round win over Fulham and manager Andre Villas-Boas is considering whether to rest everyone who started bar goalkeeper Petr Cech, who has recovered from the head knock suffered on Wednesday.
Alex is suspended and Daniel Sturridge out with a knee problem, while Michael Essien is still recovering from a long-term knee injury.
Rodgers has no fresh injury concerns ahead of his team's trip to west London.
Striker Danny Graham is set to be available after missing the 3-0 win over West Brom with a back complaint, but may have to settle for a bench spot after Leroy Lita's goalscoring exploits against the Baggies.
Left-back Neil Taylor has recovered from the blow to the head he suffered in a challenge with Peter Odemwingie but Rodgers remains short of centre-halves with Alan Tate (broken leg) and Steven Caulker (knee) injured, so captain Garry Monk and Ashley Williams will again pair up in defence. Midfielder Kemy Agustien (hamstring) and striker Craig Beattie (ankle) are also sidelined.
Chelsea (from): Cech, Ivanovic, Bosingwa, Ferreira, Terry, Luiz, Cole, Bertrand, Mikel, Romeu, McEachran, Ramires, Lampard, Meireles, Mata, Malouda, Torres, Drogba, Anelka, Sturridge, Kalou, Lukaku, Turnbull.
Swansea (from): Vorm, Williams, Taylor, Britton, Graham, Sinclair, Dyer, Dobbie, Routledge, Monk, Lita, Moore, Bessone, Moreira, Rangel, Allen, Tremmel, Gower, Richards, Lucas.
