Jones, 35, is world rugby’s most capped player with 157 Tests to his name and is one of 10 Welshmen who will take on the Springboks.
Jones is joined by Josh Adams (Cardiff Blues), Dan Biggar (Northampton Saints), Gareth Davies (Scarlets), Louis Rees-Zammit (Gloucester), Liam Williams (Scarlets), Taulupe Faletau (Bath), Wyn Jones (Scarlets), Ken Owens (Scarlets) and Justin Tipuric (Ospreys).
“I’m very proud and privileged. It’s obviously a huge privilege. To be selected in the squad is obviously where you want to be as a player. I had a call from Gats on Sunday,” said Jones.
“It was actually a missed call so I thought I had better call him back. We had a chat and he offered me the captaincy. I accepted, obviously. I’ve got a huge amount of pride to be able to add this to my CV but there is a huge amount of work for us to do when we get out there for the games.
“I told my nearest and dearest but kept it pretty tight. It’s nice that it’s out there now. The significance isn’t lost on me. A few of the home nations played South Africa at the last World Cup and to do it again is an honour.
“To go from my first tour in 2009 to now feels like a lifetime ago. I enjoy my sport and want to continue.”
