Jonny Gray joined the Warriors as a Scottish Rugby Elite Development player in the summer of 2012 after a number of standout displays for Hamilton and Scotland under-20.
The younger brother of former Glasgow favourite Richie Gray, Jonny spent a period of time before his arrival at the Warriors training and playing in New Zealand, having been named as one of the recipients of the 2012 John Macphail Scholarship.
He was called up to the Scotland U20 set-up at the age of 17 in 2012 and was made captain when he returned to the national age-grade squad in 2013 for the RBS 6 Nations.
In the summer of 2013 he signed a three year deal with the Warriors and in November of the same year made his full Scotland debut during the Autumn Tests, after an impressive start to the 2013/14 season.
Jonny made his RBS 6 Nations debut for Scotland in February 2014, as a substitute against England.
He captained the Warriors for the first time against Connacht at The Sportsground in a 31-13 on 25 April, 2015.
