Team news
Luke Wright suffered a toe injury when he was struck by the bowling machine during practice and is doubtful and Dimitri Mascarenhas has been called up as cover. Graham Onions could be in line for his ODI debut as England try to freshen up the team, or Graeme Swann is the other option depending on whether the conditions suit two spinners.
England (possible) 1 Andrew Strauss (capt), 2 Joe Denly, 3 Ravi Bopara, 4 Matt Prior (wk), Owais Shah, 6 Eoin Morgan, 7 Stuart Broad, 8 Adil Rashid, 9 Tim Bresnan, 10 Ryan Sidebottom, 11 Graham Onions.
Australia's one-day machine continues to run smoothly and the only reason to change would be to assess various options ahead of the Champions Trophy. James Hopes missed out at Lord's with Ricky Ponting returning, while Ben Hilfenhaus and Peter Siddle haven't played a game yet in the series.
Australia (probable) 1 Shane Watson, 2 Tim Paine (wk), 3 Ricky Ponting (capt), 4 Michael Clarke, 5 Callum Ferguson, 6 Michael Hussey, 7 Cameron White, 8 Mitchell Johnson, 9 Nathan Hauritz, 10 Brett Lee, 11 Nathan Bracken.
