Scott McTominay will miss out again for Scotland while Lyndon Dykes is a doubt for the visit of Denmark.
Manager Steve Clarke delivered the fitness update ahead of the final World Cup qualifying Group F encounter after earlier calling up Celtic right-back Anthony Ralston for the first time.
McTominay missed Friday’s 2-0 win over Moldova with a throat infection and the Manchester United midfielder, one of eight Scotland players who are a yellow card away from suspension, has not re-joined the squad.
QPR striker Dykes joined up with the squad after missing the 2-0 win in Chisinau through suspension, but he is a doubt for Monday’s Hampden clash as he bids to overcome a knock and illness.
Manager Steve Clarke said: “Scott is definitely out. Scott hasn’t recovered enough from his virus.
“Lyndon didn’t do very much this morning. Lyndon, I would put at 50-50.”
Ralston comes into the squad after Nathan Patterson picked up a suspension during Friday’s win over Moldova, which sealed a play-off place.
The 22-year-old has made 23 appearances for Celtic this season after seizing his chance under Ange Postecoglou.
Motherwell’s Stephen O’Donnell is the other right-back in the squad but is also among the players who are one yellow card away from missing the play-off semi-final in March.
Scotland are looking to boost their chances of sealing a home semi-final when they host the Group F winners.
