Former Scotland rugby captain Doug Keller has died at the age of 81.
He will be buried in Sydney on Thursday after losing his battle with a long-standing illness at the weekend.
Dr Keller, who was born in Australia and played six Tests for the Wallabies before moving to London, qualified for Scotland through his grandmother.
Having started his career as a prop, he won seven Scotland caps in 1949 and 1950 as a blindside flanker and also played for London Scottish.
Scottish Rugby Union president Bert Duffy said: "Doug Keller made a magnificent contribution to our great game and I know his loss will be felt in both the Scottish and Australian rugby communities.
"On behalf of Scottish Rugby, I extend our sincere condolences to his family."
Dr Keller had a reputation as a tough, uncompromising player and made his international debut for the Wallabies in 1947.
After the 1947-48 tour to Europe, he moved to London to continue his studies as a specialist urologist, a field in which he was later to become a world authority.
Dr Keller was called up for Scotland's Five Nations match against France in 1949.
He captained the Scots to an 8-0 win in Paris and led the side for the remainder of the 1949 Five Nations campaign, at the end of which Scotland finished fourth on points difference with two wins and two defeats.
Keller was replaced as captain the following season by back-row colleague Doug Elliot but played the first three matches of the 1950 championship.
His last international appearance came in the 21-0 defeat by Ireland at Lansdowne Road.
Scotland went on to finish second, again with two wins and two defeats.
Dr Keller passed away at Mona Vale Hospital on Sydney's northern beaches on Saturday.
