Sydney - Rugby World Cup back James O'Connor said on Monday he would miss Australia's home internationals against Scotland and Wales next month because of a liver injury.
O'Connor, 21, underwent scans on a lacerated liver on Monday, hopeful of being cleared to make an early return to Super Rugby with the Melbourne Rebels and in time to be considered for Wallabies selection.
The Rebels said the scans revealed that while the laceration was healing well, O'Connor would not be able to return to full contact training for another month.
Another scan would then be needed to determine when he would be able to return to play, the club said.
O'Connor tweeted his news after receiving the result of the scan.
"Disappointing result-Liver healing very nicely just going to run out of time...if only I had a couple more weeks up my sleeve," he said on Twitter.
O'Connor suffered the injury against the Waratahs on April 21 when he was accidentally kneed by Berrick Barnes, but was hopeful of playing against Scotland and Wales.
Australia take on Scotland on June 5, before facing Wales in three Tests on June 9, 16 and 23.
With O'Connor now out of the running, Rebels team-mate Kurtley Beale or fit-again Quade Cooper are in contention for the Wallaby No 10 jersey.
