Didier Drogba has been ruled out of Chelsea's trip to Aston Villa on Saturday, but John Terry will be considered for selection.
Drogba will not travel with the squad to the Midlands for the 5.30pm kick-off as he is suffering from the effects of a fever.
However, skipper Terry, who missed England's midweek Euro 2012 qualifier against Montenegro with a back problem, has been passed fit to play.
Manager Carlo Ancelotti has also revealed that Alex, Frank Lampard, Daniel Sturridge, Salomon Kalou and Yossi Benayoun all remain sidelined.
Portugal full-back Jose Bosingwa will return to the bench after almost 12 months on the sidelines with a knee ligament injury.
"Frank Lampard is not available, Drogba is not available, Sturridge is not available, Kalou is not available, Alex is not available, Benayoun is not available, Terry is available," explained Ancelotti.
"Lampard is getting better but he needs to have some weeks again, maybe two weeks to be fit 100 per cent, he had a problem on his adductor and we have to pay attention. He is working individually and needs two weeks again.
"Drogba had a fever this week and was not able to train. He started today but is not fit. He took antibiotics in the last days and needs to train next week and I'll know if he is available for the game in the Champions League.
"Alex may be available next week and also Kalou will surely be available for the Champions League, and Sturridge needs days of recovery."
