Amla, 36, is one of South Africa's all-time great one-day international players but his recent form has been poor, while increasing age has meant that he has slowed down in the field.
Amla scored only 51 runs in four innings in South Africa's shock Test series loss against Sri Lanka earlier this year and did not play in the first three one-day internationals against the tourists, although Cricket South Africa stressed he had not been dropped.
He was due to play the final two one-day games against Sri Lanka but withdrew because his father was seriously ill.
