"I'm over the moon to be selected," said Sean. "When I joined Glasgow I was looking to try to continue my rugby career and the prospect of playing for Scotland, although an ambition I cherished, wasn't uppermost in my mind."
Sean has been in outstanding form for Glasgow in their recent Celtic League matches.
