All-rounder Dean Elgar will replace injured batsman JP Duminy in South Africa's Test squad in Australia, Cricket South Africa said on Sunday.
Elgar will leave for Australia later this week once his visa formalities have been completed, CSA said.
"We have opted for a like-for-like replacement," CSA selection convener Andrew Hudson said in a statement.
"Dean can bat anywhere in the top order and he also gives us a back-up spin bowling option.
"He is currently in good form and made 76 with a strike rate of 107 in the Chevrolet Knights' only 50 overs' game to date.
"He had a good debut for the Proteas in their recent ODI series in England and he fully deserves his call-up to our Test squad as well."
Duminy was ruled out for the rest of the three-Test series with Australia after he ruptured his Achilles tendon while warming down kicking a rugby ball after the end of play at the Gabba on Friday.
