The Dragons were hopeful that he would be back in domestic action later this month but coach Darren Edwards confirmed he will not play again before the Wallabies arrive at the Millennium Stadium for a World Cup third-place play-off rematch on December 3.
"When he first got back it was a four-to-six-week injury so it quite possibly could be Australia if Wales pick him as his return match," said Edwards.
"It's disappointing for us here at the Dragons that we can't get him out there on the field but that's the nature of rugby."
