Lyons ruled out

Australia number eight David Lyons has been ruled out of the World Cup, after fracturing his left leg in the Wallabies' 37-6 win over Canada.

Lyons fell awkwardly early in the second half and was helped from the field before being sent for x-rays, which confirmed he suffered a fractured fibula.

Australia team doctor Martin Raftery said: "The normal recovery period for a fractured fibula is between three and four months. It would certainly be impossible for him to return to play during the World Cup."

The Wallabies are likely to send for a replacement before next weekend's quarter-final against England.

ACT Brumbies loose forward Jone Tawake, veteran Matt Cockbain and lock James Horwill were all on the Wallabies' stand-by list.

But Australia have suffered major injury problems in their back division - and may yet decide to replace Lyons with a player from a different position.

The Wallabies currently have Stephen Larkham (knee), Stirling Mortlock (shoulder) and Scott Staniforth (shoulder) sidelined.

Coach John Connolly said: "We haven't yet thought about a replacement but we do have the option to bring someone else across, and we will consider that over the next 24 hours or so."
