Springbok scrumhalf Joost van der Westhuizen spent Friday evening in bed recovering from a food bug that has affected seven of the 26-strong national squad.

Van der Westhuizen, due to play his 75th Test, is the player to have been hit the hardest and although he took part in the captain's run, he was put to bed early in a bid to get him back to full strength in the next 24 hours.

Other players who took strain on Thursday included Conrad Jantjes, Cobus Visagie, Ollie le Roux, Joe van Niekerk, Willie Meyer and Johan Ackermann. By Friday, they were feeling a lot better.

The Bok medical staff were confident Van der Westhuizen would make the necessary recovery, but made no secret of their concern at his condition on Friday.

The Boks completed their preparations with a captain's run at Eden Park. It was not a session conducted in ideal circumstances as New Zealand's pay channel 'Sky Sport' spent the afternoon setting up for Saturday's match.

In the light of the spy allegations that clouded the Boks preparations in Perth, the management were understandably annoyed at the presence of cameras at the ground, even though the pay station's staff gave the assurance nothing was being recorded.

The session, scheduled to be a closed session, could also not escape the attention of some 70 former All Blacks who attended a function at Eden Park - a gathering that overlapped with the Boks only visit of the week to the Test match venue.

Earlier in the day, Bok coach Harry Viljoen confirmed that Andre Snyman would replace the injured Robbie Fleck in the only change to the starting XV that drew 14-all against the Wallabies.

Fleck had been given until Saturday morning to prove his fitness, but on Friday morning he informed the Bok management that he was not confident that his right ankle would stand up to the rigours of a Test match.

Snyman, whose Test comeback has been dubbed remarkable following to broken ankles in two years, will play an international for the first time since 1999.
