Australia delay team announcement

Australia have delayed naming their team until 13:00 BST on Thursday for Saturday's Pool A decider with Wales at Twickenham because of injury concerns.

Coach Michael Cheika was due to announce the line-up at 08:00 BST.

But the former Leinster boss will wait until after their Thursday training session to do so - with Wales naming their team at 11:00 BST.

Australia's Israel Folau (ankle) and wing Rob Horne (shoulder) are doubts while Michael Hooper is suspended.

Waratahs full-back Folau came off in the 66th minute of the 33-13 win over England last weekend.

Flanker Hooper pleaded guilty after being cited for an act of foul play against England, when the Wallabies vice-captain failed to use his arms when clearing full-back Mike Brown out at a ruck.

Ben McCalman and Sean McMahon are vying to take over from Hooper in Australia's back-row.

And Curtley Beale would the the likely stand-in for Folau if the latter is ruled out.

Cheika says he "would not be surprised" if Wales counterpart Warren Gatland partners Justin Tipuric with captain Sam Warburton on Wales' flanks.

And Wallabies scrum-half Will Genia says Gareth Davies has "been one of the best" nines at the tournament.
