Australia to delay naming their side to face Argentina

Australia will delay naming their team for Sunday's World Cup semi-final against Argentina until this afternoon.

The Wallabies have injury concerns over number eight David Pocock (calf), full-back Israel Folau (full-back) and prop Scott Sio (elbow) and will give the trio one last training session to prove their fitness for Sunday's Twickenham showdown.

"After training we'll decide. It's a World Cup semi-final so it's not like we're keeping anyone for next week," head coach Michael Cheika said.
