Quade Cooper may be forced to miss the Wallabies' end-of-season tour of Europe after scheduled surgery to repair a knee injury was delayed.
Cooper was due to undergo arthroscopic surgery on Friday to remove a small chip of cartilage from the knee he injured during last year's RWC.
The surgery was delayed because of a cut Cooper suffered during Australia's Rugby Championship Test with Argentina last week.
Cooper said the operation will now take place in a week to ten days.
His recovery from the surgery is expected to take four to six weeks and the delay threatens his availability for the tour, starting November 10 against France.
