India selectors are expected to choose between specialist batsman Rohit Sharma and all-rounder Hanuma Vihari for the series-opening test against Australia in Adelaide starting Thursday.
The pair, named in a 12-man roster released by the Indian board on Wednesday, will battle for the number six slot vacated by injured fast-bowling all-rounder Hardik Pandya.
Rohit played the last of his 25 tests against South Africa in January but has experience in Australian conditions, having toured with the side in 2014-15.
One-test spin bowling all-rounder Vihari made his debut against England at The Oval in September, scoring 56 in the first innings
