Interim boss Benitez's bid to improve his record of 10 wins in 21 matches in charge continues with the Barclays Premier League clash at home to Wigan on Saturday could take place without his first-choice goalkeeper.
A statement on the club's official website read: "Petr Cech is returning to Chelsea due an injured finger and will not take part in Czech Republic's international fixture on Wednesday.
"The injury will be assessed at Cobham by the club's medical department.
"Czech Republic are playing a friendly away against Turkey ahead of two World Cup qualifiers in March."
