Chelsea will be without the services of Republic of Ireland winger Damien Duff for tomorrow night’s FA Cup fourth round replay with Everton at Stamford Bridge.
The Irishman lasted just five minutes against Liverpool after coming on as a substitute during their 2-0 win before being forced out of the action with a muscle problem.
Coach Jose Mourinho has confirmed Duff is likely to be out for a maximum of two weeks.
Didier Drogba remains unavailable due to his involvement in the African Nations Cup with Ivory Coast who have reached the last four of the competition.
Right-back Paulo Ferreira is doubtful with a thigh injury and England Under-21 international Carlton Cole is struggling with a groin problem.
Provisional squad: Cudicini, Cech, Johnson, Gallas, Carvalho, Terry, Huth, del Horno, Lampard, Essien, Maniche, Gudjohnsen, Makelele, Diarra, J Cole, Crespo, Robben, Wright-Phillips.
