Queensland teenager Luke Morahan will link up with the wounded Wallabies for the final fortnight of their grand slam tour after fullback Adam Ashley-Cooper suffered a minor quad strain in Australia's 20-20 stalemate with Ireland.

With centres Berrick Barnes (ankle), Stirling Mortlock (calf) and Rob Horne (hamstring) all ruled out of the tour, Wallabies coach Robbie Deans has drafted in Morahan as backline insurance after Digby Ioane (shoulder) also ended Sunday's Test battered and bruised.

The Wallabies fly to Edinburgh on Monday to prepare for three games in a week to conclude the tour.

Saturday's Test against Scotland at Murrayfield will be followed by a Tuesday night clash with Cardiff and the tour finale against Wales on Saturday week at Millennium Stadium.

Morahan is an Australian sevens representative who made his debut for the Reds during this year's Super 14 before suffering a season-ending shoulder injury.

He will link with the Wallabies in Edinburgh, where Deans is hoping his young squad - with an average age of just 24 - bounces straight back after Ireland captain Brian O'Driscoll scored in the final minute at Croke Park to deny Australia the chance to complete a sweep of wins over the four home nations.

"Obviously they're hurting now and they're not enjoying that, but they'll hang tough and they'll pick themselves up and we'll push on," Deans said.

"There's still a lot of things that they can be proud of and we've got a good week's work ahead of us.

"We've still got the incentive of leaving these shores unbeaten."

Despite the near miss in Dublin, Deans believes it was another step forward for the rebuilding Wallabies, who went oh so close to ending Ireland's eight-Test winning run with a team featuring just five survivors from Australia's 2007 World Cup quarter-final loss to England.

"So this group is really making headway and we've got a lot of fun in front of us," he said.

"It's evident the team's making progress, as are individuals within it.

"Quade (Cooper) is a good example of a bloke who a year ago was just a kid. He's growing into a man.

"You could look across the board and any number of them (are similar). There's not too many that have been around for too long."

At just 21, David Pocock is another case in point.

Selected to start ahead of veteran flanker George Smith, Pocock was named man of the match at Croke Park in a dominant display from the entire Wallabies forward pack.

"The scrum was magnificent. I've never seen it go better than that," Deans said.
