All-rounder Cameron Green will miss a substantial part of Australia's Cricket World Cup build-up after being struck on the head by a ball from Kagiso Rabada during the first one-day international against South Africa on Thursday.
An Australia team spokesperson confirmed on Friday that Green will undergo an eight-day concussion protocol during which he will be monitored by the team's medical staff.
He is unlikely to be available until the fifth and final match in Johannesburg on September 17.
