The Wallabies' forward stocks continue to take a battering with key prop Sekope Kepu joining David Pocock on the sidelines ahead of Australia's return Rugby Championship match against New Zealand in Auckland on Saturday.
Captain Pocock was ruled out for the remainder of the competition after undergoing keyhole surgery on his right knee and in a further blow for the Wallabies Kepu was scratched late Tuesday with a knee injury.
The powerful prop sustained a grade two strain to the medial ligament of his right knee in training on Tuesday, an injury that can typically put a player out of action for a month.
It was another cruel blow for the struggling Wallabies after confirmation Pocock would miss up to three months, also putting him in doubt for the Wallabies' November spring tour.
The surgery was required after Pocock damaged the articular cartilage in last Saturday's match with New Zealand in Sydney.
