Chelsea boss Jose Mourinho says winger Pedro and striker Loic Remy are not in the squad to face Dynamo Kiev in the Champions League.
The two join goalkeeper Thibaut Courtois and defender Branislav Ivanovic on the sidelines.
The Belgium international will be out until December damaging his medial ligaments in September.
The Serbian was injured while on international duty for Serbia last week.
"They [Pedro and Loic Remy] have little injuries, both," Mourinho told reporters.
"It is nothing really important, but not possible for tomorrow. Big risk for tomorrow. So no risk.
"We have other options. We have other players. Especially because they are in positions where we really have other options. So no risk."
