Australia's Pucovski under injury cloud for fourth Test against India
"He will continue rest and rehabilitation over the next two days before a decision is made on his fitness for the fourth Test match."
Losing Pucovski could cause headaches for the Australian top order after the 22-year-old stepped up to replace Joe Burns, who struggled in the first and second Tests.
Injury woes have also hit the India camp ahead of the Brisbane Test, with Ravindra Jadeja ruled out with a dislocated thumb.
The tourists have already lost fast bowlers Mohammed Shami, Umesh Yadav and Ishant Sharma to injuries while batsman KL Rahul was out ahead of the third game with a sprained left wrist.
The teams flew to Brisbane on Tuesday with the four-Test series tied at 1-1 ahead of final game at the Gabba starting Friday.
