The 29-year-old was chosen to the Proteas’ provisional roster for the competition, which begins on October 5, but is unable to travel.

Nortje will now miss his second World Cup in a row due to a persistent back ailment.

Sisanda Magala, 32, has also been forced to withdraw from the squad due to injury.

Both men played in Australia’s 3-2 home one-day international series win earlier this month.

With a fractured thumb, Nortje missed the 2019 World Cup, and Cricket SA stated, “It was decided that the risk associated with his inclusion in the squad outweighed his obvious value to the team.”

Magala was limited to four overs in the third ODI of the five-match series against Australia due to a knee injury.

To replace the injured pair in South Africa’s 15-man squad, white-ball coach Rob Walter has called up all-rounder Andile Phehlukwayo and fast bowler Lizaad Williams.

It was “hugely disappointing” for Walter to lose Nortje and Magala, but he noted, “This provides an opportunity for Andile and Lizaad on the global stage.” They have excellent skill sets.”

South Africa kicks off their World Cup campaign against Sri Lanka on Saturday, October 7 in Delhi.
