Australian batsman Phil Hughes remains in a critical condition after being struck on the head by a short ball and will have scans on Wednesday.
The 25-year-old is in hospital in Sydney after collapsing during a Sheffield Shield match.
“A further update will be provided when the results of the scans are known,” team doctor Peter Brukner said.
Cricket Australia also confirmed that the current round of Sheffield Shield matches has been abandoned.
The South Australia left-hander was carried off on a stretcher after a delivery from New South Wales bowler Sean Abbott struck him on the head, missing his helmet.
Hughes was subsequently taken to hospital where he was placed in an induced coma following surgery.
The match was abandoned after the incident, and Cricket Australia says the games between Victoria and Western Australia, and Queensland and Tasmania have also been called off.
“We’ve spoken to players and the Australian Cricket Association, and given how players across the country are feeling right now, it’s just not the day to be playing cricket and we understand that,” Cricket Australia’s executive general manager of team performance Pat Howard said.
Hughes’s ex-Australia team-mate Nathan Bracken says players are aware of the potential dangers they face every time they play cricket, and says he and Abbott will have the backing of the wider cricket community.
“I think there is respect and an understanding that every player has about the risks they take when they go out there,” former left-arm seamer Bracken, 37, told BBC World Sport.
“It’s great to see that support for Phil and for Sean. Phil is a player who is well liked in cricket, a bloke who has worked very very hard to get where he is.
“Let’s hope the fight that he goes through now gets him back out there doing what he wants to do.”
