Valerie Adams coach Jean Pierre Egger suffered a knee injury during travel to the recent Diamond League meeting in Monaco which is going to prevent him travelling to Rio with the double Olympic shot put champion.
The subsequent surgery and rehabilitation and the risks associated with travel means that Egger will be unable to attend the Rio Olympic Games.
The news is very disappointing for Egger and Adams as they complete the lead-in to the Games. Following the injury, they have been working on strategies to ensure that the fantastic form she is coming into is fully realised at Rio.
Adams competes on the first day of the Rio Athletics programme on 12 August.
Adams physiotherapist Lou Johnson will accompany her to the Games and Athletics New Zealand High Performance Director Scott Goodman will also be assisting in Rio with technical support.
