The game kicks off in Rosario, Argentina at 8.45pm today (Monday) and is live on Sky Sports 3.
Head coach Mark Mapletoft said: “This is a good chance for the whole squad to end the tour on a high.
“We've looked at all the South African games. They've clearly had a change of emphasis from last year and previous years. They are very comfortable ball-in-hand, they've got some exciting runners and they combine ambition with some traditional South African forward play which we will need to combat to ensure we maintain dominance throughout the game.”
