It's disappointing for Andy as his recent good form earned him a place in Scotland's squad preparing for the Six Nations, but with the squad training in Stirling today, the injuries have left him sidelined.
Andy's club captain, Jon Petrie, still has sore ribs and Scotland coach Matt Williams indicated he'll probably miss Glasgow's Celtic League game against Neath Swansea Ospreys on Saturday.
Calvin Howarth attended today's Scotland training session but was sidelined due to a tight back muscle.
