South Africa head coach Rassie Erasmus have given a debut to prop Zachary Porthen in their starting XV for the Autumn International series test against Japan and switched Cheslin Kolbe from wing to full-back for Saturday’s clash at Wembley Stadium.

Porthen, 21, is a former Junior Springbok captain who has played a handful of games in the United Rugby Championship for the Cape Town-based Stormers, but has impressed Erasmus enough to start.
