Former Australia lock Dan Vickerman has died at the age of 37 at his family home in Sydney.
Vickerman, who won 63 caps for the Wallabies, leaves a wife Sarah and two sons, and authorities are yet to comment on the cause of his death.
He moved to Australia from his native South Africa in 2001, joining the Brumbies, and he went on to spend five seasons with the Waratahs.
His Test debut for Australia came in 2002 and, after playing in a second World Cup in 2007, he moved to England and spent three years earning a degree in land economics at Cambridge University.
During that time, Vickerman played in two Varsity matches and also had a short stint with Northampton.
He returned to Australia to continue his career with the Waratahs and also forced his way back into Australia's side, securing a place in their 2011 World Cup party.
Vickerman made his final international appearance in the semi-final of that tournament and was forced to retire in 2012 after persistent problems with stress fractures in his right leg.
Australia Rugby Union chief executive Bill Pulver said: "The rugby world is in shock today after news of the tragic passing of Dan Vickerman.
"Dan was an uncompromising competitor who forged a wonderful international rugby career despite a number of injury setbacks along the way.
"A much-loved character off the field. He cared deeply about the game and the players, helping players transition into life after rugby in his role with (the players association) RUPA following his retirement.
"Our thoughts and prayers are with Dan's family at this extremely difficult time."
England coach Eddie Jones, who coached Australia and the Brumbies, 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."
Further tributes poured in for Vickerman with former team-mate, and close friend, Phil Waugh saying: "We all have huge admiration for the guy that he was.
"He's a guy that necessarily wasn't the loudest in the team, but had the most respect from everyone playing with him. There's so many positive memories of him on and off the field."
Another former Wallaby, Matt Burke added: "Very abrasive as a player but a great lad, great tourist, a very good player and was just one of the good lads that you enjoyed his company."
