South Africa's Springboks secured a narrow 17-10 victory over Argentina in Buenos Aires, but the win came at a cost as captain Siya Kolisi suffered a hamstring injury, raising concerns ahead of their upcoming series against New Zealand. The match, part of Rugby's Greatest Rivalry, saw the Springboks edge out their South American rivals in a tightly contested encounter (news.google.com). Kolisi, who had already endured a recurrence of the injury earlier in the season, was forced to leave the field in the first half of the game (independent.co.uk). His absence could prove a significant setback for the team as they prepare for their next challenge.

The result also impacted the World Rugby rankings, with the Springboks climbing after their win, while the Wallabies narrowly avoided defeat against Japan (thesouthafrican.com). Despite the physical toll on key players, Argentina managed to field a balanced squad, even without some of their regulars (citizen.co.za). The match highlighted the Springboks' resilience, but the injury to Kolisi adds uncertainty to their preparations for the New Zealand series. The team's coach, Rassie Erasmus, will now be under pressure to find a solution to keep the captain fit (planetrugby.com).
