CAPE TOWN, South Africa -- All Blacks head coach Dave Rennie revealed that outside centre Billy Proctor suffered a "potentially" serious shoulder injury against the Stormers in New Zealand's 38-21 win on Friday.
Proctor started the first match of the All Blacks' Rugby's Greatest Rivalry (RGR) tour of South Africa, but was substituted off five minutes in the second half due to injury in an overall bruising encounter.
"We're not sure - potentially Billy Proctor. He was trying to jackal for a ball and got a cleanout. It looks like it may be a shoulder injury; I'm not sure, but there's a few bumps and bruises," Rennie said in his post-match press conference when asked if any players picked up serious injuries.
New Zealand ran in six tries to the Stormers' three, but there were passages in the game where they struggled to match the hosts' physical game.
The scores were locked at 14-14 until a late flurry of tries in the final 14 minutes saw the All Blacks come out on top.
Rennie suggested that his team against the Sharks in Durban on Tuesday in New Zealand's next game will contain several players who did not feature on Friday.
He admitted that the long-term goal is to compete with the talent reserves that have fuelled South Africa's back-to-back World Cup titles in 2019 and 2023 - but that New Zealand still have work to do in building them.
"Rassie [Erasmus] has been [building depth for the Springboks] for eight years. We're a couple of months into it," said Rennie - who was appointed in March this year.
"We've brought over a good squad. I know a lot of the guys who played tonight had big minutes in the Test series, so that's pleasing for us. We've got some good footy into them - some tough footy tonight and they're better for it.
"There will be an enormous amount of changes for the side that's going to play the Sharks on Tuesday. Tours like this are great for us to test and build depth.
"Heading into a World Cup next year, we're going to have a lot more of our group of players that we've got here and we'll use beyond this tour."
New Zealand will play South Africa in four Tests on this tour, with the first taking place on Aug. 22 and the last being held outside of South Africa -- in Baltimore, Maryland -- on Sept. 12.
