Wayne Parnell has been ruled out of the remainder of the one-day series against Australia with a rib injury.

He will be sidelined for up to a month after sustaining the injury in the second ODI in Johannesburg after what team manager Mohammed Moosajee called a "high impact landing" while fielding.

South Africa have not added anyone to the squad in Parnell's place but already have two other allrounders at their disposal. Andile Phehlukwayo, who make his debut against Ireland and has played all three matches against Australia, appears to be the frontrunner to establish himself in that position while Dwaine Pretorius, who was included in Parnell's absence at Kingsmead, is also available.

Parnell is the second South African allrounder to require time off after Chris Morris was ruled out for two months with a knee injury. Parnell's niggle means he is unlikely to feature in the first half of the domestic first-class competition, which kicked off on Wednesday but could target the T20 tournament, which begins mid-November for a comeback.
