'Rassie' and the 16 players left at home as Boks head to Buenos Aires

Springbok coach Jacques Nienaber has confirmed a 26-player squad for their opening Rugby World Cup warm-up game in Buenos Aires, with some players boarding the plane early on Sunday morning.

Nienaber aims to provide ample game time to as many players as possible to finalize the best group of 33 for the tournament, adhering to their plan of spreading the workload among the squad.

“We are naming the Rugby World Cup squad in a little over a week and it is important that we have a coach that can work on rugby detail with the players remaining in South Africa and who can keep a close eye on the progress the injured players are making,” said Nienaber. “Hence, we decided it would be best for Rassie to work with them.

“Obviously he’ll still assist the team abroad virtually, and vice-versa to ensure that the players here have all the necessary game and conditioning detail they need to tick the boxes we’d like to do with them before we travel to Cardiff for our next warm-up game.”

The traveling contingent includes players involved in the team's 22-21 victory against the Pumas: Steven Kitshoff, Vincent Koch, Trevor Nyakane (all props), Bongi Mbonambi (hooker), Marvin Orie (lock), Manie Libbok (flyhalf), Kurt-Lee Arendse (wing), Jesse Kriel, Lukhanyo Am (both centres) and Damian Willemse (utility back).
