Wales number eight Toby Faletau has been ruled out of the remainder of the tour of Australia after breaking his hand in yesterday's opening Test.
Wales were defeated 27-19 by the Wallabies in Brisbane yesterday.
Caretaker coach Rob Howley has called up Melbourne Rebels' Gareth Delve from outside his original 34-man squad, while Newport Gwent Dragons man Faletau will fly home to have his injury further assessed.
Howley's side face the Brumbies on Tuesday ahead of the second Test in Melbourne on Saturday.
