Cozier covered almost every West Indies series since 1962, and is one of the most respected cricket writer, broadcaster and historian to have come out of the Caribbean.
He had been hospitalised on May 3 for tests related to infections in the neck and legs. Cozier, whose father Jimmy was also a cricket writer, began his commentary career with the Australia tour of the West Indies in 1965.
