Aston Villa player John McGinn has been forced to withdraw from Scotland's upcoming games with Albania and Israel due to a calf injury.
McGinn is the next on the list of absentees for Alex McLeish's side, who have had a further seven players already withdraw with various injuries.
The list of casualties will be tough reading for McLeish, who is under fire to deliver positive results in the next two fixtures, having only won 2 of his 8 games in charge.
Former Scotland international Stephen McManus has called into question the severity of the injuries being endured by the players, suggesting that they are unwilling to play through the pain for their country.
In an interview for 'BBC Sportsround' McManus said: "I'm always amazed at the amount of people who decide they're going to pull out. When we used to be out with squads, there were people who couldn't wait to meet up because it was an opportunity to represent your country. "
He concluded: "They might be carrying a knock, might be under pressure from their physio at the club or manager. You play with aches, you play with pain - that's just part of the game. For me, the only reason you'd have pulled out was if you physically couldn't be on the pitch and would be putting your club at risk."
