Faf du Plessis has quit as South-Africa-captain across all three formats of cricket, but will remain available for selection, CSA announced. Du-Plessis says he wants to take a step-back from captaincy to allow a-new-generation of leaders to develop in the side, with the 35-year-old admitting earlier this year he was not looking at his future in international-cricket beyond the Twenty20-World-Cup in Australia in October.
