According to the initial information obtained by the excellent journalist Eric Engels, from Sportsnet, Kirby Dach's season might possibly be over, or at the very least, seriously in jeopardy.
Dach apparently suffered a severe knee injury.
Initial word I'm receiving on Canadiens' Kirby Dach is he has a torn ACL+torn MCL in his knee. There are more tests being done, and we'll wait for Habs to officially confirm once they're received all the info, but this puts Dach's season at risk if it ends up being the case.
