Australian opener Will Pucovski suffered a shoulder subluxation injury while diving in the field on day five of the third Vodafone Test at the SCG on Monday.
He will continue rest and rehabilitation over the next two days before a decision is made on his fitness for the fourth Vodafone Test match. No additional players have been brought into the squad for the final match.
Cricket Australia said Pucovski would continue his rehabilitation before a decision was made on whether he would play at the Gabba.
Meanwhile, the visitors are scrambling to sort out their Test XI after Hanuma vihari and Ashwin helped salvage a draw in Sydney on Monday, to leave the four-match series level at 1-1.
Pace spearhead Jasprit Bumrah is in doubt for the Gabba Test because of an abdominal injury. Bumrah received treatment for a minor abdominal strain at the SCG but continued to bowl.
India has been weakened during the series by the absence of quicks Mohammed Shami (arm), Umesh Yadav (calf), Ishant Sharma (side) and Bhuvneshwar Kumar (thigh).
Batsman KL Rahul has returned home with a wrist injury and Ravindra Jadeja is sidelined with a dislocated thumb, while Vihari (hamstring) is likely to be an enforced omission for the fourth Test.
