Petr Cech is a major worry.
The goalkeeper pulled out of yesterday's World Cup qualifier against Slovenia with a thigh strain.
Cech will undergo treatment today at Cobham but remains a doubt for the Journey to the North-East where the Blues recent record is poor.
If Cech fails to recover, he could be joined in the crock list by skipper John Terry who failed to make either of England's games this week.
He is suffering from a back problem.
Ashley Cole also missed England's win in Belarus last night as did Joe Cole.
Jose Bosingwa failed to make his match with Portugal with an injury.
Didier Drogba is also considered a non-starter.
