Jose Mourinho will take his side to Manchester United on Sunday afternoon, which could have some impact on his starting lineup at Stamford Bridge.
There is also a chance that Brazilian international Filipe Luis will feature at left-back in order to gain some match fitness ahead of the trip to Old Trafford, for which Cesar Azpilicueta will be absent through suspension.
As for the visitors, they will be without Slovenia Under-21 international Petar Stojanovic because of a thigh complaint.
Chelsea have never previously faced opposition from the Eastern European nation, but Maribor have made three previous trips to England - all of which they have lost.
