Since Sydney, India have already lost all-rounder Ravindra Jadeja to a thumb injury and batsman Hanuma Vihari due to a hamstring strain.
India will give their walking wounded every chance to prove their fitness for the series-deciding Test against Australia in Brisbane on Friday and will delay naming their starting 11 until the morning of the match, said batting coach Vikram Rathour.
Pace spearhead Jasprit Bumrah suffered an abdominal strain during the drawn third Test in Sydney while leading spinner Ravichandran Ashwin was nursing back spasms. Medical staff were monitoring them closely, Rathour said on Thursday.
"Our medical staff is looking into them, theyre working with all the players," Rathour told reporters. "So, I wont be in a position to comment exactly how it stands at the moment.
Seasoned quicks Mohammad Shami, Ishant Sharma and Umesh Yadav and batsman KL Rahul have also suffered injuries, while regular captain Virat Kohli returned home after the opening Test in Adelaide for the birth of his first child.
"I think the toughness comes from the preparation," he added. "The boys have been working out for not only this tour but also for many, many years now.
"We have the ability, even with or without injuries," said Rathour. "The 11 which will play the next match will be the best 11 you can put up on the ground. And all of them deserve to be there, they all deserve to have that opportunity to play Test cricket.
