The Waratahs have pulled out of a match against Scotland in June reducing Scotland's rugby tour of the South Pacific from four matches to three matches.
The match was scheduled to take place on June the 10th in Sydney but the fixture has now been cancelled.
"We have had confirmation from the Waratahs that due to injuries and the requirements of the Wallabies squad they would be unable to fulfill the fixture," Scotland manager Gavin Scott said on Friday.
"We have looked into alternatives but, unfortunately, nothing else fits into our tour schedule."
Scotland's itinerary was left with three tests against Australia (June 5), Fiji (June 16) and Samoa (June 23).
