"To all the fans around the world, I want to say I have recovered. I am OK and I have returned (to do commentary)," Richards said on air.

Fifties from Virat Kohli and Mayank Agarwal saw India reach 264/5 on day one at Sabina Park. Skipper Jason Holder claimed three wickets for West Indies.
India unsurprisingly retained the same team as they seek a clean sweep of all the completed international matches of this campaign and also a first-ever clean sweep of a Test series in the Caribbean.
Teams:
India: K.L. Rahul, Mayank Agarwal, Cheteshwar Pujara, Virat Kohli(c), Ajinkya Rahane, Hanuma Vihari, Rishabh Pant(w), Ravindra Jadeja, Ishant Sharma, Mohammed Shami, Jasprit Bumrah.
West Indies: Kraigg Brathwaite, John Campbell, Shamarh Brooks, Darren Bravo, Shimron Hetmyer, Jahmar Hamilton, Rahkeem Cornwall(w), Roston Chase, Jason Holder(c), Kemar Roach, Shannon Gabriel.
