Midfielder Kris Commons has withdrawn from the Scotland squad for Wednesday's friendly with Denmark with a foot injury, manager Craig Levein has confirmed.
Commons reported for Scotland duty wearing a protective boot on Monday before returning to Celtic's Lennoxtown training base for further treatment.
Celtic first-team coach Alan Thompson suggested the 27-year-old should miss the Hampden Park fixture with Denmark and Levein has announced the midfielder's withdrawal.
Commons' condition improved from Sunday into Monday, but reassessment by Scotland's medical team led to his absence being confirmed.
Asked whether Commons would be available, the Scotland boss said: "Unfortunately not - he becomes the third withdrawal.
"He's got bone bruising."
Alan Hutton and Steven Whittaker were on Sunday forced out of the match, which will provide vital preparation for the forthcoming Euro 2012 qualifiers.
Commons followed them into the treatment room after suffering the foot injury in Celtic's 1-0 win at Aberdeen in the Clydesdale Bank Premier League on Sunday.
Scotland boss Levein added: "He's quite quickly establishing himself as one of the key players within the group.
"Somebody else will have to take his place. What is hugely encouraging for me is the quality of the group as a whole is such now that the drop off (in quality) isn't significant at all."
