I don't see any specific reason in article. Is it because of pandemic or what?
Shimron Hetmyer Darren Bravo and Keemo Paul declined to tour England because of the number of corona cases and the number of people died and i can understand why they care about their health than playing the game. I do not think they can be back in the team as they will not be part of the preparation and without going through training i do not think they will be selected even if they want to return for the tour at a later time.
Nothing against their decision as it their choice but i would like to see what happens if by any chance (0.01%) WC or IPL gets a green light and the very same players taking U turn.
