South Africa off-spinner Johan Botha has been reported for a suspected illegal bowling action during the fourth one-dayer between Australia and South Africa in Port Elizabeth.
Botha was reported by the two on-field umpires, Brian Jerling and Asoka de Silva, along with third umpire Rudi Koertzen.
Match referee Ranjan Madugalle has informed both the International Cricket Council and South Africa team management of the report, as per the ICC regulations governing the reporting process.
The umpires' report cited concern over two types of delivery employed by Botha, his quicker ball and his doosra, the ICC said in a statement on Tuesday.
The report on Botha, second such instance for him -- the first being in 2006, will be handled under the ICC regulations for the review of bowlers reported with suspected illegal bowling actions.
The player will now undergo independent analysis of his action by a member of the ICC's panel of human movement specialists.
This will take place as soon as possible, and within a maximum period of 21 days from receipt by Cricket South Africa (CSA) of formal notice of the report by the ICC.
Botha will be allowed to play international cricket until the biomechanical report has been completed, at the discretion of CSA.
This is the second time Botha has been reported for a suspected illegal bowling action, the previous instance being in January 2006 after the third Test against Australia in Sydney and he was suspended from bowling the following month when testing confirmed the officials' suspicions.
Botha then underwent remedial action, was re-tested, his action at that time was found to be legal and he was able to resume playing international cricket.
Only if a player is banned from bowling twice within a period of two years from the date of the commencement of the first period of suspension is that ban for a minimum of one year.
