Wallabies strike weapon Digby Ioane will miss Saturday night's Bledisloe Cup clash in a major blow to Australia's hopes of reversing their trans-Tasman fortunes.
Ioane was on Monday night ruled out of the Suncorp Stadium encounter with the high-flying All Blacks due to a painful knee injury.
The destructive 31-Test winger copped a bad cork on the joint against South Africa more than a fortnight ago but managed to back up the week after when he scored the match-winning try in the Wallabies' 25-19 win over Argentina in Rosario.
The problem flared up again during the long flight back from South America but Ioane is expected to recover in time to be available for next month's end-of-season tour of Europe.
His absence robs the Wallabies of their most-potent ball-runner as they attempt to end New Zealand's 16-match winning streak.
