South Africa coach Heyneke Meyer fears Scotland may suss out their line-out calls

South African-born Scots Josh Strauss and Willem Nel were given all the set-piece details while part of the Springboks’ training squad four years ago.

As flanker Schalk Burger suggested in Sportsmail on Thursday, South Africa will be leaving nothing to chance and head coach Meyer said: ‘We give calls in Afrikaans, which most of the world don’t understand, but they would so we have to mix things up.’

The Scotland coach has made 11 changes to the side that defeated USA in their last Pool B clash.
