David Pocock will see a surgeon this week after injuring his knee in the Rugby Championship defeat against New Zealand in Sydney.
The Wallabies skipper suffered damage to the articular cartilage of his right knee in the first half of the 27-19 defeat match. Post match scans confirmed the injury and he is considered doubtful for round two of the tournament this weekend.
The news is a bitter blow to Aussie coach Robbie Deans as it comes immediately after he learned No 8 Ben McCalman is to undergo surgery after fracturing the radius in his foream.
The Western Force back row man was finally on the mend after suffering from a nerve injury in his shoulder, but now he faces a full three months on the sidelines.
Will Genia is standing-by to lead the Wallabies into the second clash with the world champion All Blacks at Eden Park, Auckland, this weekend if Pocock isn't fit. Earlier in the year Deans lost his first choice captain, Queensland Reds lock James Horwill, with a hamstring injury.
