Fergus joined the Warriors as a full-time pro in season 2005.
Fergus Matthew Andrew Thomson has represented Scotland at under-18, under-19 and under-21 levels and played in the double winning Glasgow Hawks team, after joining them from West of Scotland. Before that Fergus played for Howe of Fife.
As a 19-year-old Fergus appeared as a replacement for Glasgow in the match against Sale Sharks at Heywood Road in January 2003, though it was nearly two years later before he made his Celtic League debut as a substitute in the Hughenden victory against The Borders in November 2004.
His first start for Glasgow was not until three years after his debut, and that, too, was in a Heineken Cup tie, when Warriors beat Bourgoin at Firhill in January 2006. By then, he had played 20 Glasgow games as a replacement.
Fergus was selected for Scotland A's Churchill Cup squad in 2006 and 2007 and put in some stirring performances in the navy blue jersey.
He secured a regular starting slot at Glasgow last season, while his first full international cap cannot be too far in the future.
