Bernard Jackman wants to see Craig Casey get his chance against the Springboks

Bernard Jackman believes that Rassie Erasmus is probably correct in his assumption that Craig Casey will start against South Africa in Saturday's first Test in Pretoria.

South Africa head coach Erasmus has already named his team for the clash, making four changes from the XV that started against Ireland at the World Cup last year, with Damian Willemse, Steven Kitshoff and Jasper Wiese among those injured and suspended.
