Kevin is replaced by Grant Kemp in the starting XV
The Kings have been forced to make a late change to their front row to face the Stormers with Kevin Buys pulling out due to injury.
The tighthead prop will be replaced in the starting line-up by Grant Kemp, with Charl du Plessis taking Kemp's place on the replacements bench.
Director of Rugby, Alan Solomons said Buys has been withdrawn from the team due to concerns over his back following a knock he took during the game against the Bulls on Saturday.
"Kevin took a knock to the back during the game against the Bulls and is still not 100%," he said.
"Kevin is replaced by Grant Kemp in the starting XV, who moves up from the bench, with Charl du Plessis moving onto the bench for his debut Super Rugby game," he said.
