Australia centre Digby Ioane has been ruled out of Saturday's autumn international against Scotland.
The 24-year-old Queensland star has suffered a shoulder injury and is replaced in the starting line-up by Western Force's Ryan Cross.
The injury is to Ioane's right shoulder, rather than the left which required reconstruction earlier this year and sidelined him for six months.
Lachlan Turner takes Cross' place on the bench, meaning the Wallabies have now made two changes from Sunday's 20-20 draw in Ireland.
Glasgow captain Alastair Kellock is hopeful of cementing a place in the secondrow tomorrow. He has been in and out of the Scotland side so often he could have been forgiven for expecting the worst when the starting line-up was named.
However, he was never likely to lose his place in what emerged as an unchanged XV for the second autumn international at Murrayfield.
The 28-year-old lock performed solidly enough on his 18th cap against Fiji, a Test match he arguably only started due to an injury to Jim Hamilton.
And with his rival from Edinburgh out for the entire November Test programme, Kellock now has a real opportunity to
"Every chance you get is a massive opportunity and it's great getting back-to-back games," Kellock said. "But you look at them in isolation and try to make sure you go out and give it your absolute all.
"You don't know how many opportunities you're going to get to play for your country; each one is huge, and I'm relishing the fact that I've got another one tomorrow."
