Kirby Dach is injured, and according to some, his season may be over. Tony Marinaro and Eric Engels both seem certain that this will be the case, based on the information they've received.
It's really unfortunate, but not as unfortunate as seeing people rejoice in it. Indeed, some Blackhawks fans are satisfied to see their former player sidelined due to injury, which is absolutely dreadful.
Honestly, regardless of the team, taking joy in a player's injury is downright despicable. We'll spare you the details, but Dach doesn't deserve this hatred, nor does any other player, for that matter.
