Scotland head coach Steve Clarke says Kieran Tierney's early exit from Scotland v Republic of Ireland was purely precautionary after the Arsenal star's head knock.
The Celtic hero - who left the Hoops in 2019 for £25m - was substituted with a head injury, despite wanting to carry on. Fellow full-back Aaron Hickey was also substituted with a hamstring problem as former Celtic pair Jack Hendry and Ryan Christie netted to seal a 2-1 Nations League win ahead of facing Ukraine on Tuesday.
Clarke said of the injuries and Scotland's latest game as a whole: "Kieran was precautionary in the first-half - he got a knock and the doctor decided to take him off. Aaron was also precautionary.
