Rebels captain Dane Haylett-Petty returns for his side's must-win match against the Western Force while the Reds have welcomed back a number of players from injury for their top of the table clash against the Brumbies.
Here's all your team news for the final round of the regular Super Rugby AU season.
Western Force v Melbourne Rebels at McDonald Jones Stadium in Newcastle. Kick off: 3pm AEST, Saturday 5 September.
After more than a month sidelined because of a knee-injury, Haylett-Petty returns at fullback for the Reds' must-win clash against the Force in Newcastle.
The Test fullback's return has forced a tweak to his side's backline, with Reece Hodge shifting to outside-centre where he will partner Billy Meakes. Matt To'omua shifts to fly-half and Andrew Deegan drops to the bench, while Tom Pincus has been promoted from the bench to take the right-wing position with Andrew Kellaway dropping out of the 23.
Up front and the tight-five remains the same, while there's just the one change to the back-row with Richard Hardwick coming into the starting side for Brad Wilkin who is on the bench.
On the bench and Australian sevens star Lachie Anderson is in-line to make his debut.
Force coach Tim Sampson has also tweaked his side for their final match of the season.
Like the rebels, there's just one change to the forward pack with Brynard Stander starting at openside flanker for Kane Koteka who will come off the bench.
In the backs, World Cup-winning All Black Richard Kahui drops out of the side and his absence sees Byron Ralson start on the right-wing and Kyle Godwin shift one closer to the action at outside centre.
Force (1-15): Pek Cowan, Andrew Ready, Kieran Longbottom, Jeremy Thrush, Ollie Atkins, Fergus Lee Warner, Brynard Stander, Henry Stowers, Ian Prior (c), Jono Lance, Marcel Brache, Henry Taefu, Kyle Godwin, Byron Ralston, Jack McGregor

Queensland Reds v Brumbies at Suncorp Stadium in Brisbane. Kick off: 7:20pm AEST, Saturday 5 September
Reds coach Brad Thorn has welcomed back a couple of key backs from injury while there's a tweak to the forward pack too.
Harry Hoopert returns to the starting side at loose-head porp.
He's the only change to the forward pack, which has been bolstered by experienced on the bench by the returns of the Smith brothers - JP and Ruan.
But it's in the backline where there's been a couple of key changes.
Hamish Stewart is fit to keep his spot at inside centre, but he's joined by Jordan Petaia who comes off the bench to wear the jersey he wore for the Wallabies in last year's quarter-final loss to England in Japan.
Chris Feauai-Sautia returns on the right-wing, while the exciting Hunter Paisami is back in the folder after recovering from his injury quicker than expected.
Brumbies coach Dan McKellar has also welcomed back some star power.
After missing for the past fortnight, experienced Wallaby Tevita Kuirdrani returns at outside centre and his return sees Solomone Kata back to the bench.
Test halfback Nic White comes in for Joe Powell, who drops out of the squad altogether and has been replaced by Ryan Lonergan.
Up front there's a couple of minor changes too, with Scott Sio rotating in for his Wallabies teammate James Slipper while Folau Fainga'a will start ahead of Connal McInerney at hooker.
Darcy Swain comes in for Murray Douglas in the second-row, as does Rob Valetini for Lachie McCaffrey.
While the Brumbies have already locked up top spot and will host the final on September 19, McKellar said he was pleased to bring in some experience as they look to end the Reds' undefeated run in Brisbane in 2020.
"It's great to be able to recall players with so much experience into the side this week," McKellar said.
"Whitey has been great for the group since returning and the likes of Folau and Tev have been training really well over the past couple of weeks and have earned their place in the team.
"The Reds are undefeated at Suncorp Stadium this year and we haven't played our best up there in the last couple of years so we know the challenge in front of us and we'll be up for it on Saturday night."
