Hooker Tatafu Polota-Nau has been ruled out of the Wallabies' Rugby Championship and Bledisloe Cup opener against the All Blacks with a knee injury suffered in Saturday's Super Rugby final.
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 win over the Crusaders.
His injury compounds the Wallabies' front row problems because hooker and captain Stephen Moore has already been ruled out for the remainder of the season with a knee injury.
Nathan Charles, who has played only two tests, will likely start in place of Polota-Nau against New Zealand at Sydney on August 16.
The All Blacks have won the Rugby Championships the last two years and are unbeaten in their last 17 tests.
Has Wallabies coach Ewen McKenzie done the right thing by resigning?
