The South African international prop joined Saracens from Cape Town Super Rugby franchise The Stormer in the summer of 2016. He’ll join a growing group of former Stormers at Allianz Park along with Schalk Burger, Neil de Kock, Schalk Brits and Michael Rhodes.

Koch was identified by Saracens as a player with enormous potential who could make a significant contribution to the squad at tighthead prop. Known as a powerful scrummager with great ability around the park, he is knocking on the door for a regular spot in the Springbok front row having made his debut in the 2015 Rugby Championship clash against New Zealand.
