Eli Walker will replace Liam Williams in Wales' World Cup squad ahead of their quarter-final against the Springboks.
The winger was named in the original squad, but was forced to pull out days before the tournament began with a hamstring problem.
Walker is unlikely to play on Saturday, but could come into the equation if Wales progress to the semi-finals.
George North and Alex Cuthbert are the only other wingers in the squad with North also a candidate for outside centre, which is where he played against the Wallabies.
