Cape Town - South African-born flank CJ Stander has been named in Ireland's starting XV for the third and final Test against the Springboks at the Nelson Mandela Bay Stadium in Port Elizabeth on Saturday.
Kick-off is at 17:00.
Stander was red-carded in the opening Test at Newlands (which Ireland won 26-20) after a late tackle on flyhalf Pat Lambie.
He was subsequently banned for one match, missing the Boks' 32-26 victory in the second Test at Ellis Park in Johannesburg last weekend.
Altogether, Ireland coach Joe Schmidt has made five changes in personnel and one positional switch from the team that went down at Ellis Park.
Fullback Jared Payne has been ruled out and his place will be taken by Tiernan O'Halloran, who came off the bench last week.
The uncapped Matt Healy is named amongst the replacements as is Eoin Reddan, who has announced that he will retire from rugby after the match.
Hooker Rory Best will captain Ireland for the 12th time and is re-joined in the front row by Mike Ross, while loosehead prop Jack McGrath is set for his third start of the tour.
Devin Toner and the versatile Iain Henderson reunite in the second row, with flanks Stander and Jordi Murphy returning to the back row to link up with No 8 Jamie Heaslip, who scored his 13th try for Ireland last weekend.
Conor Murray continues his partnership with Paddy Jackson at half-back for what will be his 50th cap. The Limerick man will be the third scrumhalf after Peter Stringer (98) and Eoin Reddan (70) to hit the half-century for Ireland.
Luke Marshall returns to the starting line-up and switches to outside centre with his Ulster colleague Olding retaining the No 12 jersey. Andrew Trimble and Keith Earls complete the back-three alongside O'Halloran.
