Wales coach Warren Gatland has suffered a foot injury during a fall from a ladder in New Zealand.
The 48-year-old Kiwi's return to Wales has been delayed as he recovers from the incident on Easter Monday.
WRU chief executive Roger Lewis said: "We all wish Warren a speedy recovery from the injuries he has suffered in this extremely unfortunate accident."
Gatland's assistants will cover his duties during his recovery.
Gatland was cleaning windows when he lost his balance and fell three metres onto concrete taking the full impact on his heels.
He suffered multiple fractures to the right calcaneus and also a fracture to the left calcaneus. Consequently, he is in leg casts and requires surgery by the leading orthopaedic surgeon in the Waikato to reconstruct his right heel.
The injury he suffered is not expected to have any major impact on the continuing preparations for scheduled Wales matches in June 2012.
Lewis added: "Knowing Warren as I do I can reassure the Welsh rugby public that he has diligently put the people and processes in place to ensure he stays closely linked to what is happening in the game back here in Wales.
"I have spoken to Warren on a number of occasions since his fall and have told him he will lead the tour to Australia unless anything unforeseen happens in the prognosis for recovery we are working to."
