Mitchell Marsh will have to wait until later this month to find out whether he will require surgery on the ankle problem he suffered at the IPL after scans showed "a moderate to high grade" injury.
Marsh is unable to see a specialist under he completes his 14-day quarantine period on October 10. Speaking earlier this week he was hopeful he would be able to avoid surgery and had his sights set on pushing for a return late in the opening stages of the Sheffield Shield which will be played in an Adelaide hub.

"Scans have revealed that Mitch Marsh has suffered a moderate to high grade syndesmosis injury to his right ankle, which he sustained in the Sunrisers Hyderabad's opening match in the United Arab Emirates early last week," a WACA statement said.
"A specialist will further assess Mitch's ankle once he is out of hotel quarantine next Saturday 10 October to determine if surgery or non-surgical management is required. Return to play timelines will be mapped out once he has completed quarantine and met with the specialist."
Meanwhile, Western Australia have named a 17-man squad for the Sheffield Shield hub. Players will take part in Premier cricket over the weekend before self-isolating from Monday prior to heading to Adelaide later next week. Their first match is against South Australia from October 10.
Ashton Agar, who was part of the limited-overs tour of England and has been quarantining in Adelaide, will link up with the squad when they arrive in the city.
Off-season signing Cameron Gannon, the former Queensland quick, is in line for his Western Australia debut while uncapped pair Corey Rocchiccioli and Lance Morris have been included.
"We're ready to go and can't wait to get over to Adelaide and begin the season," head coach Adam Voges said. "It's a tight knit group, the commitment of the players during the pre-season has been excellent and this will hold us in good stead as we enter the hub.
"This will be a season like no other, we are well prepared to tackle the challenges that present throughout the year."
Western Australia squad Ashton Agar, Cameron Bancroft, Hilton Cartwright, Cameron Gannon, Cameron Green, Liam Guthrie, Aaron Hardie, Josh Inglis, Matt Kelly, Shaun Marsh, David Moody, Lance Morris, Joel Paris, Corey Rocchiccioli, D'Arcy Short, Ashton Turner, Sam Whiteman
