(Video) George Smith knocked out as Wallabies trail Lions at half-time

British and Irish side dominant at the scrum to take a handy lead into the break.

Australia suffered an early blow in the third Test match against the British and Irish Lions after prodigal son George Smith was knocked out after a head clash with Richard Hibbard.

The Lions dominated the first half thanks to their scrum and the boot of Leigh Halfpenny as they led 19-10 at half-time.

But two penalties to the hosts after the break and the Wallabies got back into the game.
