Bit of a myth that Doig is doing well. This season he lost his place in Verona side and since moving to Sassuolo has not played at all.
Brown is almost certainly out with injury as is Nisbet.
Our squad will probably be something like this:-
Gunn, Clark, Kelly
Hickey (if fit), Patterson, Porteous, Hendry, Hanley, Souttar, Robertson, Tierney
McGinn, McGregor, McTominay, Ferguson, McLean, Gilmour, Christie, Armstrong
Dykes, Adams, Shankland, Fraser
