The depth of the Wallabies front-row stocks is being tested before a minute's even been played in this year's Rugby Championship with three players out injured for the competition opener.
Prop Scott Sio was the latest casualty after rolling his ankle at training on Monday. He joined hookers Tatafu Polota-Nau and Stephen Moore, both suffering from knee complaints, on the injury list.
Sio would be replaced by Melbourne Rebels tighthead Laurie Weeks for the Wallabies' opener against the All Blacks in Sydney on August 16.
Sio has returned home to Canberra for scans to determine the extent of the injury, with the Wallabies believing it's a potential syndesmosis injury.
His replacement, Weeks, would join the squad in Bathurst on Wednesday when the NSW Waratahs also entered the camp.
The Wallabies said they chose a tighthead as replacement for Sio - who played loosehead - as they had plans to train the young frontrower up as a tighthead.
At hooker, Polota-Nau underwent scans today and was found to have a low-grade medial crucial ligament strain.
He limped from the field at halftime on Saturday night during the New South Wales Waratahs' 33-32 Super Rugby final win over the Crusaders.
Nathan Charles, who has played only two tests, would likely start in place of Polota-Nau.
Wallabies first choice starting hooker Stephen Moore was out for the season.
