Scotland duo Adam Ashe and Alex Dunbar have been sent home to Glasgow after both were ruled out of the Dark Blues' RBS 6 Nations opener with England.
The Warriors pair met up with Vern Cotter's squad for their three-day training camp in St Andrews earlier this week.
But the players - who both missed last year's World Cup - will have to wait to make their Scotland returns after being counted out of the February 6 clash with England.
Centre Dunbar has not played for his country since tearing knee ligaments in the build-up to last year's clash with the English.
He was hoping to make his comeback against Eddie Jones' side but then suffered a thigh strain in his club's 22-5 win over Racing 92 on Saturday. He had the injury scanned at Glasgow's BMI Ross Hall Hospital, with medics confirming he will have to be sidelined for a few weeks yet.
Ashe picked up a shoulder injury in Glasgow's Champions Cup loss to Northampton a fortnight ago and is also unlikely to be ready to feature until later in the Championships.
A Scottish Rugby spokesman said: " The pair will continue their recovery and ongoing assessment under the care of the Glasgow Warriors medical team."
