Junior Springbok coach Chean Roux has made three changes to his starting team to face New Zealand in their U20 Championship pool decider in Rosario on Wednesday.
Two of those changes come in the pack as lock Elrigh Louw and flank Sibusiso Sangweni earn their first starts of the tournament.
They replace Emile van Heerden and Celimpilo Gumede respectively.
The final change comes in the backline as Thaakir Abrahams also gets a first start on the wing in place of Caleb Dingaan.
The winning team will gain automatic entry into the semi-finals as the Pool C leaders, while the losing team will have to rely on log points and possibly points difference to snap up the last semi-final spot.
The SA U20s are currently the top team in Pool C with a narrow one-point points difference over New Zealand after both sides won their opening two matches with bonus points.
