Tighthead prop Zachary Porthen regains the captaincy for the Junior Springboks' final Under-20 Rugby Championship match against Argentina at the Sunshine Coast Stadium in Bokarina, Queensland on Sunday.
Porthen leads a much-changed side to the one which lost 24-19 to hosts Australia on Tuesday. Lock JF van Heerden led the Junior Boks against the young Wallabies, but will resume his role as vice-captain alongside centre Jurenzo Julius.
Porthen missed the Australia clash because of a hand injury, but he is back in a starting line-up featuring several changes.
