Scott McTominay sat out Scotland training on Thursday as Steve Clarke continued his preparations for Sunday’s World Cup opener against Haiti.
The 29-year-old Napoli midfielder was conspicuous by his absence at the Atrium Heath Training Centre in Charlotte, North Carolina after going down with a stomach complaint.
Dinamo Zagreb defender Scott McKenna, also 29, was another absentee as he nursed a knock.
However, both men are expected to be fit as the Scots get their Group C campaign under way on Saturday.
Scotland will head into the game looking for a fast start to the competition with Morocco, who made the semi-finals in Qatar four years ago, and five-times winners Brazil waiting in the wings.
Former Scotland goalkeeper Cammy Bell meanwhile insists veteran Craig Gordon deserves to get the nod against Haiti.
At 43, the Hearts keeper has battled through a catalogue of injuries during his career and has played very little club football this season.
However, Gordon has been backed to take the field for his country in Massachusetts.
Former Rangers keeper Bell, who saw at close hand how hard his international colleague worked to recover from a knee injury earlier in his career, told BBC Scotland Sport’s World Cup podcast: “I had a really good relationship with Craig at that point, I’d been in squads with him, so I saw him go through that difficult time.
“It’s hard to watch such a talented goalkeeper and a guy who is so determined – and a brilliant personality as a person as well, a great human being – go through such dark days.
“But again, this is why he went through them, this is why he’s come out into the light at the end of the tunnel, if you want to call it that.”
