Reds playmaker Quade Cooper says that having played for 120 minutes over two matches after coming back from knee surgery he is ready to play against Scotland in Newcastle next week.

The Reds have a bye this weekend in Super Rugby and their next match is in Melbourne against the Rebels on June the 29th. As Cooper will not play for the Reds this weekend he is available to play for the Wallabies.

The Wallabies have been experiencing a dire run with injuries to their prospective number 10s ahead of the home internationals against the Scots, followed by three Tests with Wales.

Kurtley Beale (shoulder), fellow Melbourne Rebels star James O'Connor (liver laceration) and Brumbies pivot Christian Lealiifano (knee) are all sidelined leaving Cooper as the only specialist number 10 in Robbie Deans' 39-man train-on squad announced on Sunday.

The injuries have increasing Cooper's chances of regaining the jersey after shaky performances at last year's World Cup in New Zealand.

The mercurial Queenslander ruptured knee ligaments himself in the World Cup play-off for third place against the Welsh seven months ago.

But 24-year-old made an impressive 40-minute return in the Reds' 34-20 Super XV win over the Golden Lions before playing out the whole 80 minutes in Saturday's 13-12 victory over the Brumbies.

Despite his limited playing time, Cooper believes he is ready to lead the Wallabies' attack against the Scots.

"I'm very confident. I've only played one game and a half and felt good when I was out there," Cooper said.

"It's a matter of just keep ticking the boxes and keep moving along. If I get the opportunity, I'll put my hand up and give it everything I've got."

Meanwhile Wallabies coach Robbie Deans confirmed that Reds and Wallabies captain James Horwill damaged his right hamstring in the Reds' 13-12 win over the Brumbies in Canberra on the weekend which could rule him out for a month.

"James, we are presuming, is out for the whole of June but it is not as bad as it first looked," Deans said of the injury.

"It looked pretty sinister."
