The Six Nations champions welcome the Rugby Championship winners to Cardiff on Saturday without a number of key players.
Injuries have robbed them of several stars, while a few more are also unavailable thanks to this match sitting outside the testing window.
As a result, Pivac has been largely limited as to who he can choose this weekend.
Gareth Anscombe, who hasn’t played for Wales since August 2019, starts at the opener ahead of Rhys Priestland, while Dragons full-back Taine Basham completes the back row alongside regional teammates Ross Moriarty and Aaron Wainwright.
Johnny McNicholl starts at the back, while Johnny Williams gets the go-ahead at 12.
Pivac also made a late post-announcement change to his squad, with Ken Owens being ruled out. Ryan Elias moves from the bench to the starting lineup, while Kirby Myhill – who teamed up with the team during their training camp at the Vale Resort – moves on the bench.
Elsewhere among the substitutes, Seb Davies offers back-row coverage, while Ben Thomas is also lining up as a substitute after making his Wales debut this summer.
Hooker Elliot Dee has been released from the Wales squad due to the neck injury he suffered against the Stormers a fortnight ago. He will now return to his region to continue his rehabilitation.
Pivac is facing the media soon and you can follow his press conference live below.
Wales team: Johnny McNicholl; Owen Lane, Jonathan Davies, Johnny Williams, Josh Adams ; Gareth Anscombe, Tomos Williams; Wyn Jones, Ryan Elias, Tomas Francis, Adam Beard, Alun Wyn Jones (c), Ross Moriarty, Taine Basham, Aaron Wainwright.
