Euan first played pro rugby for Glasgow but has since represented Northampton Saints, Newcastle Falcons and Agen, before joining Worcester Warriors.
Euan’s first senior Scotland appearance was in the non-cap international win against the Barbarians in May 2005, and he went on to gain his first cap as a replacement against Romania in Bucharest 12 days later.
He went on to become the 33rd player to reach the milestone of 50 or more caps for Scotland when he took to the field for the 2013 Calcutta Cup match at Twickenham.
Euan was selected for the 2009 British & Irish Lions, his tour was curtailed due to an ankle injury.
He played for three of Scotland’s age-grade squads – under-18 in 1997-98, under-19 in 1998-99 (including the FIRA world junior championship in Wales), and under-21 in 1999-2000 (including SANZAR tournament in Auckland, New Zealand) and 2000-01.
He is a former pupil of Williamwood High School, East Renfrewshire, and a product of the Glasgow Southern club (now GHA), but he moved to Glasgow Hawks for the 2001-2002 season.
While with Southern, he played for Glasgow Schools’ under-16 team, visited New Zealand with the Glasgow Thistles’ development squad, and played in Glasgow teams who won the district under-18 and under-19 championships.
In summer 2003 he joined Glasgow Rugby on a full-time professional contract, scoring a try on his Celtic League debut against Cardiff.
