I am actually new to cricket game . I have seen many times that players got badly injured due to ball being hit . Mostly players belongs to middle and lower class families . Just like army Is there any committee who take action about these type of circumstances that happened?
ICC is not responsible for any tragedy related to players and ICC will not give funds to injured players but their boards will rescue them in terms of funding.
If the injury happens in a game being played in a competition organised by a specific cricket board or organisation, that organisation MAY have insurance for this sort of eventuality, or they may not. You'd need to enquire with the organisation in question to get a specific answer.
