Cheslin Kolbe will make his first start at full-back for South Africa when they face Ireland at the Aviva Stadium on Saturday.The world champions have made three changes to the team that beat Argentina in their final Rugby Championship match in September, with Kolbe restored to the starting line-up after recovering from a broken jaw.Damian Willemse is given the nod at out-half while Kurt-Lee Arendse replaces Canan Moodie on the wing.Former Munster centre Damian de Allende continues his midfield partnership with Jesse Kriel, with Jaden Hendrikse preferred to Faf de Klerk at scrum-half.The pack is unchanged with captain Siya Kolisi joined by Pieter-Steph du Toit and Jasper Wiese in the back row, while Eben Etzebeth and Lood de Jager are the second row combination.Malcom Marx is selected at hooker ahead of Bongi Mbonambi, who forms part of a powerful bench that includes Ox Nche, Vincent Koch and Franco Mostert.South Africa have again opted for a 6-2 split on the bench, De Klerk and Willie le Roux the two backs named among the replacements, and head coach Jacques Nienaber said Kolbe will provide cover at 10."Cheslin has delivered star performances for his clubs in France at fly-half, so he will slot in as a back-up fly-half if necessary, while Faf is another option for us at No 10 as well," said Nienaber."Damian Willemse can also move to inside centre if we need cover there, while Damian de Allende can play outside centre and Willie full-back, and this allowed us for us to opt for a six-two split on the bench."We need your consent to load this comcast-player contentWe use comcast-player to manage extra content that can set cookies on your device and collect data about your activity.
