Over the last couple of days, there has been discouraging news on the corona virus front. Several people connected with MLB and the NFL have tested positive and some franchises have been forced to close facilities. This includes the Lightning.
Yesterday it was reported by a number of news sources that Toronto superstar Austen Matthews has also positive, although I don't think that has been confirmed by the Maple Leafs yet. If eventually confirmed, that could change everything, including the NHL's willingness to go forward with the 2019-20 season.
