Adriaanse joins the squad to replace Sharks’ teammate Tendai Mtawarira, who is out with a neck injury he suffered during the 31-30 victory over Wales in Nelspruit this past Saturday.

Lewies on the other hand will be replacing Flip van der Merwe, who sustained a serious knee injury during the same game against the Welsh.

“Tendai has a bulging disc in his neck and he will consult with a specialist in Durban as soon as possible,” Springbok team doctor Craig Roberts said.

“Flip hyper-extended his knee in a tackle and scans confirmed our clinical suspicions of a posterior cruciate injury. He will consult a knee specialist in Pretoria later on Tuesday.”

Springbok coach Heyneke Meyer said Adriaanse and Lewies were the next players on the standby list and is hopeful that they will gel with the rest of the squad.

“Lourens has been with us before and I’m sure he will slot back in easily,” said Meyer.

“Stephan was part of our training squad in Durban at the end of last month. He arrived in Port Elizabeth earlier today and looked good at our afternoon training session.

“He has been very good in Vodacom Super Rugby this year and deserves this opportunity.”
