The ICC has suspended South African off spinner Johan Botha for bowling with an illegal action.
The ban takes effect immediately and has been handed down after independent analysis found that Botha was bowling with an illegal action during South Africa's third Test with Australia last month.
The ban will apply until Botha can show he has remedied his action.
"The independent report has identified excessive levels of straightening in both his off-break and doosra deliveries," ICC General Manager David Richardson said.
"It is now up to Johan to remedy the concerns that have been identified ahead of a reassessment which will be necessary if he is to return to international cricket."
"Johan is a young player and there is nothing to stop him making a successful return to international cricket with a remodelled action."
It is the first time that Botha has been reported under the regulations for the review of bowlers with suspected illegal actions.
