AB de Villiers has been withdrawn from all cricket for at least a month due to a back injury.
Cricket South Africa's decision to rest De Villiers for the next "four to six weeks" means he will not be available for IPL side Delhi Daredevils in the Twenty20 Champions League tournament, which takes place in India from October 8-23.
"AB de Villiers developed left lumbar pain, four weeks ago, during preparation for the ICC Champions Trophy tournament," said Shuaib Manjra, chairman of CSA's medical committee.
"Despite extensive physiotherapy and medication, his symptoms persisted and without medication he was unable to move freely during the ICC Champions Trophy.
"We have thus decided to withdraw AB from all cricketing activities for the next four to six weeks in order to allow for proper management of his condition and prevent further injury."
De Villiers added: "I am obviously disappointed to miss the Champions League and I wish the Daredevils all the best for the tournament."
