On Monday afternoon the J9 Foundation confirmed that Joost van der Westhuizen, the former South African captain and scrum-half, had died aged 45. Shortly after his passing, he was heralded as a 'South African great', a 'giant and warrior of rugby' and a 'fighter until the end'.

Van der Westhuizen was rushed to hospital in a critical condition on Saturday, and was placed on life support after his key organs began to fail as a result of motor neuron disease. He had been diagnosed with a form of the disease in 2011 and initially given only two and a half years to live.

The scrum-half played in 89 Test matches for South Africa, scoring 38 tries and winning the Rugby World Cup in 1995. He was inducted into the International Rugby Hall of Fame in 2007, and is widely regarded to be one of the greatest number nines to have played the sport. "The world of rugby mourns the passing of a South African great," World Rugby tweeted following the news of his death.

Leading rugby union players and clubs immediately took to Twitter to share their tributes, with the South African rugby community coming together to honour one of their greatest players.

The South African Rugby Union shared a picture of the player along with a tribute reading: “RIP Joost van der Westhuizen, 1971-2017. Condolences to the family and friends of a true Springbok hero.”

The South African Minister of Sport, Fikile Mbalula, also shared the news, along with a short statement praising the legacy of a "great giant and warrior of South African rugby".

"The passing of Joost is a sad chapter in South African sporting history," Mbalula wrote. “His contribution to our national rugby team was immense.

“He leaves behind a generation of athletes who aspire for his legendary sportsmanship. We draw lessons from his fighting spirit in bith the field playing for our national team and against motor neuron disease.

"South Africa is poorer without this great giant and warrior of South African rugby."

Former Springbok Tonderai Chavhanga meanwhile commented:

A number of British rugby legends, all of whom played against Van der Westhuizen on a number of occasions, tweeted following the news to express their sadness.

English World Cup winners Matt Dawson and Will Greenwood, both of whom lined up against Van der Westhuizen in a 25-6 Pool C victory en route to winning the Webb Ellis Cup in Australia, praised the 45-year old as a "great friend" and "true warrior".

And Brian O’Driscoll, the former Ireland captain, added: "RIP Joost van der Westhuizen. An incredible player and fighter to the end. The first of the new age 9's."

Clubs and organisations including Saracens, and the English, Irish and Welsh Rugby Football Unions shared moving tributes to a man that played an integral part in the Rainbow Nation side that famously won the 1995 World Cup.

The tributes to Van der Westhuizen were not only limited to the world of rugby. South African cricket legends Jacques Kallis and Graeme Smith also posted warm tributes to their compatriot.
