Australia on Monday called up former All Blacks prop Aidan Ross for the third and final test against the British and Irish Lions, while wing Harry Potter was ruled out injured.
Ross, who was born in Australia before moving to New Zealand as a child, will join the squad as the Wallabies try to avoid a 3-0 series whitewash in Sydney on Saturday.
The Lions won the first test in Brisbane 27-19 and the second at Melbourne 29-26.
"Aidan Ross will join the squad in Sydney to help the team prepare for the final test of the British and Irish Lions series," the Wallabies said on social media.
"Harry Potter will remain in Melbourne after sustaining a hamstring injury."
Ross played his sole test for the All Blacks in July 2022 against Ireland and has now completed World Rugby's mandatory three-year gap before switching allegiances.
The 29-year-old was at Chiefs since 2017, playing his 100th game in their Super Rugby final triumph in June, but he will switch to Reds next season.
Potter started the second test against last weekend, but hobbled off 20 minutes into the game with replacement scrum-half Tate McDermott playing as wing.
Wallabies coach Joe Schmidt has several options to replace Potter, including Dylan Pietsch, Filipo Daugunu and Corey Toole.
