The world of rugby has been paying tribute to former South Africa scrum-half Joost van der Westhuizen, who has died at the age of 45.
The 1995 World Cup winner had a five-year battle with motor neurone disease before he was admitted to hospital on Saturday morning.
The scrum-half, who won 89 caps for the Springboks, is widely recognised as one of the great players in his position in world rugby, and fellow professionals have been paying tribute on social media.
The official South Africa Rugby page tweeted: "RIP Joost van der Westhuizen, 1971-2017. Condolences to the family and friends of a true Springbok hero."
Brian O'Driscoll added: "RIP Joost van der Westhuizen. An incredible player and fighter to the end. The first of the new age 9's."
Former England centre Will Greendwood added: "Rugby has lost a true warrior today - #joostvanderwesthuizen - 1995 World Cup Final - Titanic Individual Performance. Rest in Peace."
Former South African cricket Jacques Kallis also posted his condolences on Twitter. He said: "RIP Joost. Thoughts and prayers with his family and friends."
Lucas Radebe, a former captain of the South Africa football team, added: "Sad news abt the passing of former springbok Joost Van Der Westhuizen @Springboks".
