The Wallabies have lost one of their most potent attacking threats for tomorrow night’s World Cup semifinal against the All Blacks, with fullback Kurtley Beale ruled out.

Beale had been touch-and-go all week as he battled through a hamstring injury suffered in last Sunday’s quarterfinal win over South Africa.

The gifted 22-year-old, who was one of five nominees for last year’s International Rugby Board Player of the Year award, was withdrawn at today’s captain’s run at North Harbour Stadium.

While Beale did take part in some of the drills, he was unable to stride out confidently enough.

That confirmed for the player and coach Robbie Deans that he wasn’t ready to play.

The versatile Adam Ashley-Cooper now moves from centre to fullback, with Queenslander Anthony Faingaa slotting in to the No13 position.

Rob Horne comes on to the Wallaby bench.

Meanwhile, tonight is the Wales and France clash for a place in the Rugby World Cup final.

A young Welsh side is trying to control their nerves while the French are summoning the full range of emotions.

Coaching France is guaranteed to give you a few sleepless nights and today Marc Lievremont admitted he is feeling the pressure ahead of tonight’s semifinal.

Speaking through a translator, Lievremont said that he will be able to sleep in 10 days time after the final.
