South Africa edge Argentina in thriller but Kolisi suffers injury

South Africa scraped past Argentina 17-10 in Test rugby at the possible expense of inspirational captain Siya Kolisi in Buenos Aires on Saturday.

Kolisi, in his first match in seven weeks following a hamstring injury, trudged off in the 25th minute. He may be a doubt to lead the Springboks back home against New Zealand in two weeks in the opening Test of the blockbuster Greatest Rivalry series.
