South Africa pick Willemse over Le Roux for World Cup opener
Willie le Roux, the long-time first-choice number 15 for the Springboks, is among the replacements with the versatile Willemse preferred against Scotland, who are likely to take the game to South Africa with ball in hand.
Wingers Kurt-Lee Arendse and Cheslin Kolbe make up a pacey back three, and Damian de Allende and Jesse Kriel are a change to the centre pairing from the side that thumped New Zealand by a record 35-7 in their final warm-up game in London.
Jasper Wiese takes over at number eight from 37-year-old Duane Vermeulen, who drops to the bench, but the rest of the pack remains the same with the only backs among the replacements scrumhalf Grant Williams and Le Roux.
