Centre-backs Federico Fernandez and Kyle Bartley are doubts for Swansea City with knee injuries, while Luciano Narsingh (ankle) will be assessed.
Renato Sanches (hamstring), Leroy Fer (Achilles) and Wilfried Bony (knee) are long-term absentees. On-loan striker Tammy Abraham is ineligible to face his parent club.
Chelsea defender Marcos Alonso serves the second of his three-match suspension but otherwise the Blues have no fresh injury concerns.
Swansea City have won one of their 13 Premier League matches against Chelsea (D4 L8), a 1-0 victory in April 2016.
The Swans have beaten Arsenal and Liverpool this season and could become the first team from outside the top six to win three matches against these clubs in 2017/18.
A Chelsea win, in Antonio Conte's 73rd match, would make him the third-quickest manager in PL history to reach 50 wins, behind Jose Mourinho's 63 matches and Pep Guardiola's 69.
Olivier Giroud has scored twice and assisted twice in four PL starts at Liberty Stadium.
