According to what was just reported by François Gagnon, journalist of RDS, the young Montreal Canadiens defenseman Kaiden Guhle could miss a very long period of time:
"We're talking about an absence that could extend to three months and perhaps even put his first season with the Habs in jeopardy." - François Gragnon on RDS
In 36 games this season, the young defenseman recorded 14 points and was already establishing himself as a mainstay on the Habs' blue line
In summary, in the best case scenario, Guhle will miss 4-6 weeks, and in the worst case, his season is over.
