The Springbok Sevens have called up wing Rosko Specman in place of the injured Justin Geduld for the next leg of the HSBC Sevens World Series in Las Vegas.
The three-day USA rugby event kicks off this Friday and South Africa are the defending champions.
Geduld suffered a hamstring injury over the weekend at the Wellington Sevens, where the Springbok Sevens claimed third spot after a strong finish in their playoff match against Scotland.
South Africa head the log with 76 points halfway through the nine-tournament World Series and are seven points clear of New Zealand - who won their home event in Wellington to move into second place.
South Africa will face hosts USA, Portugal and Japan in the pool stages of the Las Vegas tournament.
