South Africa narrowly defeated Argentina 17-10 in a thrilling Test match held in Buenos Aires on Saturday, but the victory came at a potential cost with captain Siya Kolisi leaving the field due to injury.

Kolisi, returning from a seven-week hamstring injury layoff, exited the game in the 25th minute. He expressed concern about his condition, stating, "I hurt my hamstring again unfortunately. It's tough but I can't be sad about it. There's nothing I can do but go in for a scan and see how long I'm out for."

The Springboks celebrated their 12th straight Test win, yet the match was not without its tensions. The resilient Pumas nearly equalized at the end, launching a relentless attack with a tap penalty right in front of the Springbok posts. They executed 15 phases, only for Matías Moroni to drop a high pass when unmarked, leaving Argentina Coach Felipe Contepomi visibly frustrated and Moroni in tears.

Key players for South Africa included:

• Eben Etzebeth, the caps record-holder, who played the entire match.
• Sacha Feinberg-Mngomezulu, the fly-half, also present for all 80 minutes.
• Lood de Jager, who returned from a hip injury, contributing until the third quarter.

As the Springboks prepare to face New Zealand in a highly anticipated series, Kolisi's fitness will be crucial in their efforts to maintain their winning streak.
