Scotland vs South Africa forms the final fixture of Scotland's summer tour. It is also the only barrier standing between the Scots and a clean sweep of wins from these four games.
The South Africa game in Port Elizabeth undoubtedly provides coach Vern Cotter's sternest test yet. Previous tour wins have come against USA, Canada and an under-strength Argentina. South Africa, buoyed by their last-gasp win over Wales, will present an entirely different proposition.
Scotland captain Grant Gilchrist knows that Scotland will need to improve from the Argentina game to challenge the Springboks.
"Next week's the biggest challenge of the tour and we'll need to be up again another few levels if we want to compete."
South Africa have released seven senior overseas-based players ahead of the game. This list of players includes: Bryan Habana, Wynand Olivier, Bakkies Botha, Francois Louw, Gurthro Steenkamp, Schalk Brits and Morne Steyn.
Scotland have themselves called up three Glasgow players to bolster their squad ahead of the final game. Euan Murray, Tyrone Holmes and Adam Ashe are all included for the Port Elizabeth Test.
Scotland have never beaten South Africa on their own turf. It would be a huge surprise if Vern Cotter's side managed to change this statistic on Saturday. Here are the battles they must win if they are to do so.
