Sad announcement from the NHL about Guhle and it's confirmed

We spoke about it this morning but it is now confirmed:

After an unnoticed slash from the bench on Travis Konecny of the Philadelphia Flyers last night, the young defenseman will be punished.

After being hit solidly in the corner by Travis Konecny, Kaiden Guhle decided to retaliate against Konecny by striking him with his stick while he was sitting on his team's bench (the Canadiens' bench) and as his opponent was passing in front of him.

Yes, it's an illegal action according to NHL rules.
