Konstantinos Karetsas will be assessed before kick-off as the Greece teenager battles to be fit to face Scotland in World Cup qualifying on Thursday.
The 17-year-old Genk winger made a big impression when he came off the bench to make his international debut in the 1-0 Nations League defeat by the Scots in Piraeus in March.
He started for the first time in the return game at Hampden Park three days later, scoring his first international goal and set up another in the 3-0 win that took the visitors into League A while relegating Steve Clarke’s side to League B.
But, before the teenager trained with his team-mates at Hampden on Wednesday night, head coach Ivan Jovanovic explained: “He’s been ill for a few days. Yesterday, he joined up with the team.
“Today, he will train and his situation will be evaluated at the training session and overnight, heading into tomorrow’s game and with the hope that he’s able to help fully going into the Denmark game as well.”
Asked if he would gamble on Karetsas’ fitness, Jovanavic added: “The question isn’t so much if it’s 50/50. We want to rely more on players that are 100% ready for their matches.”
Two experienced defenders – Olympiacos’ Panagiotis Retsos and Panathinaikos’ Giorgos Kyriakopoulos – and PAOK midfielder Dimitrios Pelkas have dropped out the squad that faced Denmark last time out.
PAOK defender Giannis Michailidis has been drafted in, while there was a first call-up for 23-year-old striker Pantelidis Pavlos, who helped Kifisias win the Greek second tier last season.
