Drogba doubt for Blues

Striker Didier Drogba remains a doubt for Chelsea ahead of tomorrow’s clash with Blackburn at Stamford Bridge.

Drogba damaged his knee in the defeat by Aston Villa and is struggling to be fit.

Michael Ballack and Wayne Bridge are still out with ankle problems while Frank Lampard is doubtful with a thigh strain that kept him out of England’s Euro 2008 qualifiers against Israel and Russia.

Provisional squad: Cech, Cudicini, Hilario, Ferreira, Belletti, A Cole, Ben Haim, Terry, Carvalho, Essien, Mikel, J Cole, Malouda, Sidwell, Pizarro, Drogba, Shevchenko, Kalou, Wright-Phillips, Lampard.
