Ricardo Carvalho could return to the Chelsea side for their Barclays Premier League meeting with Manchester City on Sunday.
The Portugal defender has been sidelined with a hamstring injury but manager Guus Hiddink is contemplating restoring him to the first XI in place of Alex.
Nicolas Anelka is the only other doubt after taking a reduced part in training today with a knock, but he is expected to be fit. The Blues are without Joe Cole (knee) and Paulo Ferreira (ligaments) for the rest of the season.
Provisional squad: Cech, Hilario, Taylor, Bosingwa, A Cole, Carvalho, Alex, Ivanovic, Terry, Mancienne, Lampard, Ballack, Mikel, Deco, Kalou, Anelka, Drogba, Quaresma, Malouda, Di Santo, Belletti, Essien.
