Ramires is out of Chelsea's League Cup third-round tie with Bolton with an abductor muscle injury.
The Brazil midfielder was substituted during the second half of the Premier League draw at Manchester City as a result of the minor problem, which will be reviewed later this week.
Striker Diego Costa (hamstring) is unlikely to feature but goalkeeper Petr Cech could start as manager Jose Mourinho plans to rotate his squad with Premier League and Champions League matches to follow in the coming weeks.
Provisional squad: Courtois, Cech, Ivanovic, Luis, Fabregas, Zouma, Ake, Ramires, Oscar, Hazard, Drogba, Mikel, Schurrle, Salah, Remy, Costa, Matic, Willian, Cahill, Terry, Azpilicueta, Christensen, Boga, Baker, Schwarzer.
Manchester City captain Vincent Kompany believes Frank Lampard's dramatic equaliser against former club Chelsea could prove to be a pivotal moment in the title race.
Premier League trophies are rarely won and lost in September, and never after five games of the season, but Kompany has plenty of experience at the business end of the competition and knows the trophy can be settled by little moments.

Ever since I have been at this club, seasons and big moments have been decided on small events like this one so I will never underestimate what it could mean to our season. It could be crucial.
Frank brings quality. The goal he scored you would have seen from him for the last 15 years in the Premier League.
He is clever and still extremely motivated.
He brings experience. It is not a word you make up, it is something that helps and it is like his goal: keeping your head cool in a moment when you are under pressure and down to 10 men - how many players would have scored that goal?
He has proven it himself in only a few minutes, which is good.
