Edinburgh Rugby scrum-half Sam Hidalgo-Clyne (21) will join the Scotland squad tomorrow (Monday) as precautionary injury cover for Henry Pyrgos, who was injured in Scotland’s 41-31 win over Argentina last night.Pyrgos suffered a concussive episode after entering the game as replacement and will now be subject to a graduated return-to-play protocol.Scotland team doctor, James Robson, expanded: “The IRB head injury assessment (HIA) trial proved its worth yesterday.”It allowed us time to assess Henry fully and ensure he received the appropriate care.”Other Scotland players received treatment for injuries that Dr Robson described as “significant bumps and bruises” but, at this time, are not considered a lasting concern.
