Prop Lourens Adriaanse has been brought into the Springboks' Rugby Championship squad as cover for Trevor Nyakane.

Nyakane has been ruled out of the first two matches with an ankle injury and will continue his rehabilitation under the supervision of the Bulls and Springboks' medical and conditioning team.

Adriaanse, who plays for the Sharks, will join the squad in Sandton on Monday afternoon. The 28-year-old has won just one Test cap for the Boks, against France in 2013.

'Trevor will continue with his medical treatment, conditioning and recovery but we obviously need to get a replacement in for the two weeks, or as soon as Trevor is declared fit. It will be a risk not to have five fit props in the squad,' said Springbok coach Allister Coetzee.

'Like Trevor, Lourens can play on both sides of the scrum and he was on our standby list. Other prop candidates such as Jannie du Plessis, Lizo Gqoboka and Coenie Oosthuizen are all injured and therefore not available.'
