Tauranga's Nathan Harris is set to celebrate his 50th game for the Gallagher Chiefs when the side face the Jaguares at in Buenos Aires this weekend.
Lock Michael Allardice will captain the team in the absence of Brodie Retallick when the Chiefs play at José Amalfitani Stadium at 10.40am on Sunday (NZ time). It will be Allardice's 40th appearance for the squad, having re-signed with the franchise for 2020.
Following a 56-20 win over the Bulls in Pretoria last Sunday (NZ time), only four changes have been made to the starting 15.
"Nathan has been a strong performer for us and for him to notch up 50 caps in the Gallagher Chiefs jersey is a notable achievement," head coach Colin Cooper says.
Harris will be joined by Aidan Ross and tighthead prop Nepo Laulala, who gets the nod ahead of Angus Ta'avao in jersey 18. Allardice will combine with Mitchell Brown at lock in the only other change to the forward pack.
