The Force have left Tatafu Polota-Nau and Matt Hodgson out of their side to face the Jaguares in Buenos Aires.
Polota-Nau, who played his 150th match last weekend, has been left out in favour of club captain Heath Tessman and rookie Anaru Rangi, while Hodgson will sit out with Isi Naisarani at openside and Brynard Stander shifted to the bench.
Adam Coleman will be pairing up with Richie Arnold, the twin brother of his Wallabies partner Rory, for the first time with the two both overcoming injuries in recent weeks.
Coach Dave Wessels said they would be wary of a dangerous Jaguares side, who have shown plenty of improvement this season.
“We’re really excited to be playing the Jaguares in Argentina, but we know that we need to improve on last weekend’s performance," he said.
“The Jaguares play a dangerous style of play and we will need to play a full 80 minutes to take the four points.”
