Mumbai’s off-spin bowling all-rounder Tanush Kotian will be leaving for Australia today to join the India Test squad in Australia as a replacement for the recently-retired off-spinner Ravichandran Ashwin.

Kotian, 26, who on Monday claimed 2-38 and scored an unbeaten 39 to help Mumbai beat Hyderabad by three wickets in a Vijay Hazare Trophy game in Ahmedabad, got the news of his Test squad selection after Mumbai’s triumph.
