Edinburgh - Lock Tim Swinson has been ruled out of the Scotland lineup to take on Australia in a Test match at Murrayfield on Saturday.
The Glasgow Warriors forward aggravated a chest injury sustained originally against Japan during training in Edinburgh on Wednesday.
His place in the starting line-up will go to Grant Gilchrist, the 23-year-old Edinburgh second-rower, who will win his fourth cap.
Gilchrist's place on the bench went to Jonny Gray, who won his first cap in the 28-0 loss to South Africa at Murrayfield last week.
But there was no place for Gray's brother, Richie, a British and Irish Lion after his faltering line-out display against the Springboks.
Later Thursday, Scotland confirmed their side after wing Tommy Seymour was passed fit after sustaining a leg injury last weekend.
One changed behind the scrum saw Duncan Weir preferred to Glasgow team-mate Ruaridh Jackson at fly-half, with Max Evans' ability to cover both centre and wing earning him a bench spot.
"The injuries we've experienced with four of our frontline backs sidelined during this series -- Stuart Hogg, Tim Visser, Alex Dunbar and Matt Scott - have meant that we've had to think long and hard about combinations and our bench this weekend," said Scotland's Australian coach Scott Johnson.
