Chelsea interim manager Guus Hiddink will welcome back Diego Costa after the striker served his one-match ban against Manchester United.
Costa scored twice against Watford on Boxing Day but missed the 0-0 draw at Old Trafford after picking up his fifth booking of the season.
Hiddink employed a very defensive team without the Spanish striker, playing Eden Hazard as a striker and Pedro and Willian in deep roles on the wing.
Gary Cahill missed the game because of a minor ankle injury, but he too is expected to be available for the trip to Selhurst Park, as is Cesc Fabregas, who had a fever.
However, Radamel Falcao is definitely out after suffering a setback to his recurring thigh problem and fellow striker Loic Remy is also a doubt.
