Wallabies and Rebels star James O'Connor will only return to playing rugby after the Super Rugby break in June and has been ruled out of Australia Tests next month.
O'Connor had scans on his lacerated liver on Monday and was hoping that he would be able to recover from the injury in time to play a few Super Rugby matches in order to warm up for the Tests.
However Rebels doctors say that while the scans have revealed that the liver laceration is healing well but he will not be able to take part in full contact training for another month.
After a month O'Connor will have further scans and a decision will be made then as to whether he can return to playing.
O'Connor picked up the injury playing against the Waratahs in Sydney on April the 21st and was immediately considered doubtful for the June Tests but he had not given up hope.
However O'Connor revealed his disappointment on Twitter after he had received results of the scan.
"Disappointing result-Liver healing very nicely jst going to run out of time...if only I had a couple more weeks up my sleeve," he tweeted.
Australia's Wallabies play Scotland on June the 5th before they have a three-Test series against Wales which concludes on June the 23rd.
O'Connor's team mate Kurtley Beale is understood to be leading the race for the number 10 jersey but Quade Cooper's return from injury will be watched closely.
