Boks change one for Rugby World Cup semis as Nkosi replaces Kolbe

Springbok director of rugby Rassie Erasmus made the change as the team looks to manage Kolbe, in the hopes that he will be 100 percent fit next week should they make the final.

The explosive wing has been nursing an ankle injury since their win over Italy in the pool stages and aggravated the injury in last weekend's quarterfinal. 

Sharks wing Sbu Nkosi moves into the starting XV, which is the only change to the team that beat Japan on Sunday.

Meanwhile Erasmus continued with six forwards and two backs on the bench to provide a balanced set of reserves. It's the same as last week's bench which featured six forwards in an effort to match Japan's intensity for 80 minutes.

Springbok team (15-1):

Willie le Roux, Sbu Nkosi, Lukhanyo Am, Damian de Allende, Makazole Mapimpi, Handre Pollard, Faf de Klerk, Duane Vermeulen, Pieter-Steph du Toit, Siya Kolisi, Frans Malherbe, Bongi Mbonambi, Beast Mtawarira. 

Replacements: Malcolm Marx, Steven Kitshoff, Vincent Koch, RG Snyman, Francois Louw, Herschel Jantjies, Frans Steyn.
