Police say Sanders was shot in the hand and stomach at a family member's 21st birthday party at the restaurant in Brits, in South Africa's North West province, on Saturday night.

He died in a hospital in the capital city of Pretoria early Sunday morning.

Sanders (42-4, 31 KOs), a heavy-hitting southpaw who fought professionally from 1989 to 2008, is best known for his massive upset of Wladimir Klitschko to win a heavyweight title in March 2003.

Sanders stopped him in the second round in Hannover, Germany.

Rather than face Klitschko in a rematch, Sanders, who was stripped of his title by the WBO, returned 13 months later to face Vitali Klitschko, Wladimir's older brother, for the vacant WBC version of the heavyweight crown.

Lennox Lewis had vacated the belt when he retired in early 2004. Klitschko and Sanders, who had several lengthy layoffs during his career, waged a pitched battle at the Staples Center in Los Angeles before Klitschko stopped him in the eighth round.

Sanders fought sporadically after the loss to Klitschko, fighting only four more times against lesser opponents over the next four years.

Sanders' true love was golf and he considered pursuing a professional career in the sport.

He retired after being knocked out in the first round by South African countryman Osborne Machimana in February 2008.
