WALES have made just one change to the side that edged out Australia in their bid to complete an autumn clean sweep by beating South Africa.

Warren Gatland brings Liam Williams in for full-back Leigh Halfpenny, who suffered a concussion in the 9-6 win against the Wallabies.

Dragons captain Cory Hill has to be content with a place on the bench with Adam Beard slotting in next to skipper Alun Wyn Jones on the bench.

His Rodney Parade teammate Ross Moriarty starts at number eight while Elliot Dee once again backs up Lions hooker Ken Owens.

There is no place in the matchday squad for tighthead Leon Brown, flanker Aaron Wainwright, centre Tyler Morgan and full-back/wing Hallam Amos.

"We have rewarded the team that faced Australia with another start this weekend," said head coach Gatland.

"Leigh (Halfpenny) misses out with concussion but it's a great opportunity for Liam (Williams) at full-back.

"We are really pleased with how the bench has gone in the first three games so we will be looking for that impact again on Saturday.

"There were a lot of tough selection calls, but that is what we want. The team that played last week was hugely impressive and there are some disappointed boys who miss out.

"We want to end the campaign with a big performance against a very good South African side."
