Rabada suffered a groin strain injury - which will take him out of the OSO matches against Australia - as well as the upcoming Indian visit an he will be out for about 4 weeks.
No replacement has been decided upon. Hendricks is in the squad - but is one of the worst selections imaginable. He will give away 120 runs in 10 overs - setting up a new world record. So a replacement is to be named and that will indicate whether SA Cricket can go further down than they already are.
