England head coach Eddie Jones led the tributes to Dan Vickerman following the former Australia international's death at the age of 37.
The passing of Vickerman, who represented the Brumbies and Waratahs in Super Rugby in addition to enjoying a short stint in England with Northampton Saints, was confirmed by the Australian Rugby Union (ARU) on Sunday
Jones handed the lock his international debut in 2002 and Vickerman went on to feature in 63 Tests, appearing at three Rugby World Cups.
In a statement released by the Rugby Football Union, Jones said: "On behalf of the RFU and myself, I would like to send my condolences to Dan Vickerman's family, Sarah and the two kids.
"He was a wonderfully committed team player and a good guy.
"He will be sorely missed by the rugby community."
Waratahs CEO Andrew Hore, who played against Vickerman for the All Blacks, said: "Dan was well respected for his on-field leadership and performance, and equally respected by all that knew him off the field.
"The shockwaves of his tragic passing will be felt right across our rugby community."
A host of Vickerman's former team-mates also paid their respects, with Wallabies skipper Stephen Moore tweeting: "Vicks was somebody everyone loved playing alongside. Learnt so much from him. Thinking of his family and team mates. Rest in peace mate."
