A training ground report on PAOK’s official website revealed that Chalkias could be out of action for a week after picking up an injury, putting him in doubt for the Greek Super League encounter.
The 34 year-old missed his side’s Greek Cup victory over Makedonikos as a result, allowing former Olympiakos Volou 'keeper Glikos to start in his place.
Twelve years younger than the former Aris man, Glikos was brought to the club by manager Fernando Santos during the summer.
Speaking at a post-match press conference after his side’s Greek Cup victory on Tuesday, Santos was quoted by Sport 24 as he gave his young shot-stopper a vote of confidence.
“If Chalkias isn’t ready [to play against Iraklis] then Glikos will play – we trust him.”
The former AEK and Benfica manager also has to deal with an injury to influential midfielder Pablo Garcia, whose chances of appearing making the trip to the Kaftanzoglio are similarly slim.
