\u201cIn terms of the lights, it started here probably when we played France in Marseille [in November 2022],\u201d he said after South Africa got their World Cup defence underway with an 18-3 win. <\/p>\n

\u201cI don\u2019t know if you\u2019ve been pitch-side but in this dome, the sound is phenomenal. You can\u2019t hear anything.<\/p>\n
\u201cIt\u2019s for us, because there are a lot of [radio] channels we are working in and talking in, it\u2019s sometimes tough for us to talk to our support staff. I think a lot of teams will have systems \u2013 is it red, is it green \u2013 for the extent of the injury or the knock and how serious it is. It\u2019s just for us to communicate with support staff.\u201d<\/p>\n
The Springboks lost influential lock Eben Etzebeth to injury during the first half of the clash in Marseille.<\/p>\n

It\u2019s a method. When I was at Munster, the call was red if it was a serious thing and we must consider a substitution.<\/p>\n
\u201cAmber is \u2018listen, let\u2019s give this guy five minutes to see if he\u2019s OK\u2019 and green is \u2018it\u2019s OK, he can go on\u2019. It was something we used Munster in 2016 or 2017 and something we continue with.<\/p>\n
\u201cIf we talk on a radio, we talk tactics. If we [also] talk to medical people about injuries, it just consumes the channels.\u201d<\/p>\n
Jones, capped 13 times by Ireland between 2011 and 2015, will leave the Springboks set-up at the conclusion of the tournament to join Steve Borthwick\u2019s England staff.<\/p>\n
