Wales need to call on their reserves, both literal and spiritual, having been hit by injuries this week. First-choice full-back Liam Williams and hard-tackling, constantly-jackling back-rower Josh Navidi have been ruled out.
But you could do much worse than having Leigh Halfpenny at full-back instead. In fact, in what could be a tight arm-wrestle of a match, Halfpenny’s vast experience and jackhammer boot could be just what the doctor ordered. Ross Moriarty is more than adequate cover for Navidi in the back row.
The really good news for Wales is that the hugely talented and influential Jonathan Davies is back at outside centre. Expect him to be in the thick of it today.
For the Boks the explosive winger Cheslin Kolbe has been ruled out, with Sbu Nkosi coming in, a solitary change that coach Erasmus insists he may have considered regardless such is Nkosi’s form and ability.
Wales: Halfpenny, North, J. Davies, Parkes, Adams, Biggar, G. Davies, W. Jones, Owens, Francis, Ball, A. Jones, Wainwright, Tipuric, Moriarty. Replacements: Dee, Carre, Lewis, Beard, Shingler, T. Williams, Patchell, Watkin.
South Africa: le Roux, Nkosi, Am, de Allende, Mapimpi, Pollard, de Klerk, Mtawarira, Mbonambi, Malherbe, Etzebeth, De Jager, Kolisi, P. du Toit, Vermeulen. Replacements: Marx, Kitshoff, Koch, Snyman, Mostert, Louw, H. Jantjies, Steyn.
