The Scottish FA have announced that three players have been withdrawn from Gordon Strachan's Scotland squad for upcoming internationals.
West Bromwich Albion winger Matt Phillips, Crystal Palace midfielder James McArthur and Newcastle United defender Grant Hanley are all out of calculations ahead of the friendly with Canada at Easter Road on Wednesday and the World Cup qualifier against Slovenia at Hampden Park on Sunday.
Albion boss Tony Pulis said: "Phillips won't be going away with Scotland.
"Morrison will go. He won't be fit for the first game but there is a chance he could be fit for the second game, which is the big one."
Palace's McArthur missed the weekend's win over Watford while Hanley is sidelined despite playing for the Magpies against Brighton & Hove Albion.
