Michael Ruru and Sef Faagase, who featured in the Barbarians' narrow win over the Classic Wallabies at Lismore, have also been ruled out through injuries suffered on Tuesday.
The Barbarians are set to name the 23 that will take on the Wallabies tomorrow.
The Wallabies take on the Barbarians on Saturday October 28, kicking off at 3pm AEDT, LIVE on FOX SPORTS and Network Ten.
