A South Africa official says the team has illness and injury concerns with its two matchwinners following a seven-wicket win over West Indies in its opening Group B match at the World Cup.
Team manager Mohammed Moosajee says pollution in New Delhi had contributed to legspinner Imran Tahir picking up a respiratory tract infection, while batsman AB de Villiers has a sore back.
De Villiers, who hit an unbeaten century on Thursday, is battling a long-standing problem. Moosajee said "we just have to manage it regularly".
Moosajee added JP Duminy had "some lower back tightness" and fast bowler Dale Steyn had bruised his side colliding with a teammate in a football match at training.
South Africa play Netherlands on Thursday.
