Samoa have made one tweak to their side that will face the Springboks at Loftus Versfeld this Saturday, with James So'oialo starting at full-back.
So'oialo was a late withdrawal from the line-up that overcame Italy with ease last weekend, as Brando Va'aulu took his place in the fifteen slot.
Head coach Stephen Betham has also made a tweak on his replacements bench where flanker Alafoti Faosilva will replace Piula Faasalele.
Samoa: 15 James So'oialo, 14 Alapati Leiua, 13 Paul Williams (capt), 12 Johnny Leota, 11 Alesana Tuilagi, 10 Tusiata Pisi, 9 Jeremy Sua, 8 Taiasina Tuifua, 7 Jack Lam, 6 Ofisa Treviranus, 5 Daniel Leo, 4 Teofilo Paulo, 3 Census Johnston, 2 Wayne Ole Avei, 1 Sakaria Taulafo.
Replacements: 16 Ti'i Paulo, 17 Logovii Mulipola, 18 James Johnston, 19 Kane Thompson, 20 Junior Poluleuligaga, 21 Brando Vaaulu, 22 Seilala Mapusua, 23 Alafoti Faosiliva.
