Fraser James Macgregor Brown made his Scotland debut as an injury replacement on Scotland's 2013 summer tour to South Africa (defeating Italy in the quadrangular tournament), a few short months after representing the Scotland Club XV team in Bourgoin-Jallieu, against their French counterparts.
His first Scotland appearance at BT Murrayfield came six months later in the second-half of the loss to New Zealand in the 2014 Autumn Test before making his RBS 6 Nations debut against France in Paris.
Brown went on to feature as a replacement in every match of the 2015 Championship before earning his first start for Scotland in the Summer Tests later that year - against Ireland at the Aviva Stadium.
His performances - both for Glasgow in their PRO12 title-winning year and internationally - to earn selection in Scotland's 31-man squad for the Rugby World Cup 2015, where he featured in all five games, starting against South Africa at St James' Park
Fraser was Merchiston Castle School captain in 2006/07 and played for Scotland in the Six Nations’ under-18 festival in the Glasgow area in April that season.
He made his under-20 international debut in February 2008, playing as a replacement in the Falkirk match in which Scotland opened their campaign in the age group’s 6 Nations, and earned his first start against England at Falkirk in March. He played in all five matches in that championship, starting in two.
The following year he led Scotland under-20 to an 18-17 victory against Wales at McDiarmid Park, Perth, on the opening day of the 2009 6 Nations but, because of injury in that match, missed the age group's other matches in that programme.
He returned to the under-20 squad for the IRB Junior World Championship in Japan in May that year, captaining the Scots against Samoa and Japan.
