Following a fierce draw in the third Test, it all comes down to Brisbane's decider from Friday, as Indian defends its Border-Gavaskar Trophy. However, it will have to do so without some top players, as latest to join the injury list is all-rounder Ravindra Jadeja, while pacer Jsprit Bumrah, too, looks doubtful.

In the first innings of the SCG Test when from a Mitchell Starc delivery he was hit on the thumb. As the physio checked in, he continued to play until the end of the innings, while he stayed unbeaten for 28, as India's innings came to an end.

Later, he was reported to have been taken for scans and did not participate any further in the game. Following the draw on Monday, the Board of Control for Cricket in India (BCCI) sent out a fresh update that he has suffered a dislocated thumb and would not take part in the Brisbane Test.

"The all-rounder will now consult a hand specialist in Sydney before he returns to India. He will then head to the National Cricket Academy in Bengaluru for further management of his injury," the update from BCCI added.

It is yet unclear how long would Jadeja be out of action, as India is also scheduled to take on England in a four-Test series at home, starting February 5. Meanwhile, Jadeja underwent successful surgery, as he posted a photo of the same on Twitter. The post read, "Out of action for a while. Surgery completed. But, will soon return with a bang!"

However, apart from Jadeja, there are three more who are in doubt for the Brisbane Test. Bumrah is reported to have hurt his abdominal muscle and was seen clutching his stomach quite a few times at SCG, while he had also left the field for a medical evaluation.

Apart from Bumrah, veteran all-rounder, Ravichandran Ashwin, along with rookie all-rounder, Hanuma Vihari, is in doubt. While Ashwin hurt his ribs during play on Monday, Vihari had pulled his hamstring on the same day, as both continued to bat until the end of day's play to earn a draw.

While further details on all the three are awaited, provided they are ruled out, India does have replacements in place, but relatively inexperienced ones. For Bumrah, either of T Natarajan, Shardul Thakur or Kartik Tyagi can come in.

As for Ashwin, he can be replaced by chinaman, Kuldeep Yadav, while Washington Sundar can replace Vihari. Although the replacements are not a part of the original Test squad, that have stayed behind in Australia since the limited-overs leg to assist the side, provided such crunch situation arises.
