Nortje's ODI absence

South African speedster Anrich Nortje has been ruled out of the fourth and fifth ODIs against Australia due to lower back spasms, having already missed the third ODI.

Bavuma sidelined, Markram to lead SA

Additionally, regular skipper Temba Bavuma will miss the fourth ODI due to a right adductor strain. Veteran batter Aiden Markram will captain South Africa in his absence. 

Injury sustained in second ODI

Nortje sustained his injury during the second ODI and was sent for scans in Johannesburg. Later, a statement was released by Cricket South Africa regarding his absence.

Nortje's impressive record

The fast bowler has been a crucial part of South Africa's white-ball teams. Nortje has scalped 36 wickets in 22 ODIs at an economy rate of 5.86.

Coetzee, Dussen to step up

Gerald Coetzee replaced Nortje in the third ODI and is likely to retain his position. While Rassie van der Dussen may return to the lineup in Bavuma's absence.

Must-win clash for South Africa

With Australia leading the series 2-1, South Africa must win the upcoming game to stay alive in the series. Hence these changes may affect their morale.
