Chelsea will face West Ham without leading goalscorer Tammy Abraham, who was forced off at Valencia after landing awkwardly on his hip.
Antonio Rudiger and Ross Barkley are back in training following lay-offs, while Callum Hudson-Odoi will also be monitored after a hamstring injury.
West Ham’s Issa Diop is banned after accumulating five cautions, while Jack Wilshere and Manuel Lanzini remain out.
Third-choice goalkeeper David Martin could make his Premier League debut.
Regular number one Lukasz Fabianski is still injured, and understudy Roberto has made several errors recently.
Meanwhile, Chelsea boss Frank Lampard expects to know by Monday the extent of the hip issue Abraham suffered in the 2-2 Champions League draw at Valencia on Wednesday.
England forward Abraham, 22, has scored 10 Premier League goals this season.
“He’s got some pain and won’t be involved on Saturday,” added Lampard.
