Roma defender Kostas Manolas left international duty with Greece due to an injury.
The centre-back had been due to feature in Euro 2016 qualifiers against Northern Ireland and Hungary.
Manolas was diagnosed with a trauma to the right side of his ribcage and was sent back to Rome.
However, Edin Dzeko will go out to Bosnia for international duty against Wales and Cyprus, as he has completed the rehabilitation process for a knee injury.
