The Wallabies have suffered yet another setback ahead of the second Bledisloe Cup test against the All Blacks in Auckland on Saturday with tighthead prop Sekope Kepu joining captain David Pocock on the sidelines.
Shortly after it was confirmed Pocock was ruled out for at least three months after undergoing knee surgery, Kepu broke down at the Wallabies training session to place even more strain on Robbie Deans' squad.
The Wallabies must win the Eden Park clash to retain hope of regaining the Bledisloe Cup in Brisbane on October 20.
Scans revealed Kepu had suffered a grade two strain to the medial ligament of his right knee, it was not immediately known how long it would be before he could add to his 17 caps.
Kepu could be replaced by James Slipper, who was propping cover on the Wallabies bench during last Saturday's Rugby Championship opener at Sydney's ANZ Stadium, won by the All Blacks 27-19.
Ben Alexander, the second most experienced prop behind 46-cap loosehead Benn Robinson, is the other option.
The All Blacks must also reorganise their front row after veteran loosehead Tony Woodcock was ruled out with a rib injury.
Canterbury and Crusaders prop Wyatt Crockett is expected to be named as his replacement when the team is named on Thursday.
Pocock, injured during the first half on Saturday, will not feature for the remainder of the Rugby Championship and is in doubt for the Wallabies end of year tour to Europe in November.
