Graeme Alexander Morrison played in both Tests on Scotland's ground-breaking 2010 summer tour of Argentina.  His leadership of the midfield defensive line was a key factor in the Scots 2-0 Test series triumph - the first time a series had been won in 50 years of touring.

Morrison won his first, second, third and fifth caps for Scotland all in the same year (2004) against Australia. He also played in the memorable 9-8 win against Australia at Murrayfield in November 2009.

Graeme’s debut was on the 2004 summer tour when he came on as a replacement in the first Test against the Wallabies. 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. He then played as a replacement against South Africa at Murrayfield in the final match of that autumn Test series. It was more than three years later in February 2008 before he returned for Scotland as a replacement in the 2008 RBS Six Nations Championship match against Wales at the Millennium Stadium, and his second start in international rugby, nearly four years after his first, followed in March that year in the Calcutta Cup victory against England at Murrayfield. He continued as first-choice inside centre for the two Tests in Argentina in June 2008, scored a crucial late try in the second game of that two-match series. Though unavailable for the autumn Tests later that year, he came back to play in all five matches of the 2009 Six Nations Championship. In November that year he scored his third international in the 23-10 win against Fiji in the Bank of Scotland Corporate match at Murrayfield.

In June 2006 Graeme made a considerable impact for Scotland A when he started at outside centre in all three matches in the Barclays Churchill Cup in Canada. Continuing at outside centre in that team, he scored a try in the November match against Australia A at McDiarmid Park, Perth, and he continued in the Scotland A squad for the four other matches in 2006-2007 – against Italy A in March, also at McDiarmid Park, Perth, and then in the Churchill Cup in England in May and June. He added to his Scotland A tries in the 37-15 win against Italy A in Mogliano, near Venice, in February 2008, and his performance there earned him a recall to the national squad for the Six Nations game against Wales six days later. Later that month he was back in the Scotland A who overwhelmed their Irish counterparts by 67-7 at McDiarmid Park, and that was followed by his return to the starting line-up in the Murrayfield win against England.

Graeme 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. He is a former pupil of Dollar Academy and 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. Before playing for Scotland in the 2009 RBS Six Nations opener against Wales he signed a new contract to stay with Warriors until 2011.

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.
