Ashley Cole has been ruled out of Chelsea's Champions League clash with Schalke on Tuesday.
The left-back is close to making his return to action after suffering a rib injury against Norwich on 6 October but he did not travel to Germany with the squad.
"Jose Mourinho believes tomorrow's game has come just too soon for the left-back and he has remained in the UK," Chelsea said on their website.
Germany forward Andre Schurrle did travel though after he recovered from a leg injury that forced him out of the 4-1 victory over Cardiff on Saturday.
Schurrle scored a hat-trick in Germany's 5-3 World Cup qualifying win over Sweden last week.
