The defender has missed the Gunners' last two games after suffering an Achilles problem while on international duty with France last week.
While there is no set date for Koscielny's return, Wenger is expected to have the defender back in contention for the November 22 weekend.
"I cannot give you any date," Wenger told reporters. "I hope he will be available after the next international break."
This Saturday, Arsenal will take on Sunderland at the Stadium of Light.
