Injuries, suspensions and international commitments mean manager Robbie Neilson is without a number of influential figures.
Goalkeeper Craig Gordon is on international duty with Scotland, while defender Michael Smith is away with Northern Ireland.
Smith is suspended for the match at Dudgeon Park in any case, as is midfielder Andy Halliday. Defenders Stephen Kingsley, John Souttar and Jamie Brandon are injured along with winger Josh Ginnelly and captain Steven Naismith.
Neilson must therefore improvise in the Highlands tomorrow night but is boosted by the availability of striker Liam Boyce. He did not join the Northern Ireland squad after his wife gave birth.
Players like Aidy White, Peter Haring and Christophe Berra could find themselves restored to the starting line-up. White is the obvious replacement for Kingsley, Haring is back from suspension and Berra may feature in central defence if Mihai Popescu is shunted to right-back.
