G-Dog first signed with Glasgow in season 2003-04 and has been a regular fixture in the side's backline since moving from Glasgow Hawks. He's highly rated by Sean Lineen who has worked with Graeme at Under 21 level.
On the announcement of him re-signing with Glasgow Warriors until 2011, Graeme said: "We've got a reasonably young core of players at Glasgow and it’s clear to see that we have progressed, and are still progressing, as a club.
"The two close games against Bath and the away win over Toulouse speak volumes in terms of how far we have come. I remember playing against Toulouse in my second season with Glasgow and it's now clear to see we've come on leaps and bounds since then.
"I'm looking forward to being part of a successful Glasgow team and achieving something special with the Warriors over the coming years."
Glasgow head coach, Sean Lineen, added: "Graeme has been with us for a while now. He has matured into a good leader and wants to establish himself in the Glasgow and Scotland no.12 jerseys.
"I’m delighted he sees the progress Glasgow are making and the ambition he has to stay and win something with Glasgow."
Graeme Alexander Morrison won his first, second, third and fifth caps for Scotland all in the same year (2004) against Australia. His first was on the 2004 summer tour when he came on as a replacement in the first Test. Earlier in the tour he had also played in the matches against Queensland Reds, New South Wales Country and New South Wales Waratahs and was heralded as the best player on the park in the Waratahs match. He scored his first international try in the historic 100-8 win over in November 2004 Japan at McDiarmid Park in Perth.
In June 2006 he made a considerable impact for Scotland A when he started at outside centre in all three matches in the Barclays Churchill Cup in Canada. Previously he was outside centre in all 10 of the under-21 internationals that Scotland played in season 2002-2003. Those honours included appearances in the IRB Under 21 World Championship in June 2003, ending with a notable 33-22 victory against England at Newbury.
A former pupil of Dollar Academy, he has studied physiology and sports science at Glasgow University. His representative rugby includes under-16 and under-18 appearances for Midland Schools and Scottish Schools and under-19 and under-21 international honours as well as Hong Kong under-16.
Graeme joined Glasgow Rugby from Glasgow Hawks in season 2003-2004 and scored a debut try in the warm-up match against Gloucester at Kingsholm. His father, Ken, played for Glasgow High School FP when the club championship was introduced to Scottish rugby in 1973, and he won a B cap against France in Bayonne in 1974 before going on to play for Hong Kong.
