South Africa have called uncapped Golden Lions prop JC Janse van Rensburg into their squad for the clash with England this weekend.
Van Rensburg replaces the injured CJ van der Linde and he will join the Springboks squad in London on Wednesday.
Van der Linde will return home to South Africa after picking up a hamstring injury at training on Monday.
"Seeing that Gurthro Steenkamp was also not feeling 100 percent on Monday and after the late withdrawal of Tendai Mtawarira ahead of the Ireland Test, we've decided it would be best to have proper cover at loosehead," said Springbok coach Heyneke Meyer.
"JC is an experienced player at Vodacom Super Rugby and Absa Currie Cup level and also captained the MTN Golden Lions very well this year.
"He's been knocking on the national door for long and this will provide an opportunity for JC to experience the Springbok culture and structures."
