Career
Greeff also played 12 Tests for South Africa. Greeff was a talented utility back, but his career was blighted by a succession of injuries: a broken hand, damaged shoulder, injured knee, and, finally, a career-ending neck injury. The only time he did not start as a fullback was in his last international appearance, against Georgia in the 2003 Rugby World Cup, when he played centre.
Although Werner Greeff scored only four tries for his country, one of them, against Australia in a Tri Nations match at Ellis Park, Johannesburg, on 17 August 2002, was voted the South African try of that year.
The Springboks, who had gone behind 0–9 after conceding three kickable penalties in the first 20 minutes, scored four tries to take a 26–9 lead with 20 minutes remaining. Australia responded with three tries and a drop-goal and led 26–31 as time expired on the clock.
The Springboks played the last ten minutes with only 14 men after Marius Joubert had been shown a red card. In March 2006, Greeff underwent neck surgery that involved the fusion of two vertebrae.
After spending six months in rehabilitation, he returned to play one game for Stellenbosch University second XV (the Victorians) against the University of Cape Town in September 2006 and scored a try within the first 20 seconds.
He was named in the Stormers" squad for the 2007 Super 14, but, after playing in a pre-season warm-up game against a Boland team, continuing concerns about the neck injury forced him to announce his retirement from rugby on 22 January 2007. Already the owner of a fast-food outlet in Cape Town, he indicated that it was his intention to pursue his business interests.
