NHL Player Safety comes for Ducks forward Ross Johnston

This just in, NHL Player Safety has fined Anaheim Ducks forward Ross Johnston $2,864.58, the maximum allowable under the CBA, for roughing Seattle Kraken forward Tye Kartye.

And here's the play in question:

Johnston absolutely mugs Kartye from behind and delivers a sucker punch to the jaw. I would actually have no problem with a game suspension here, the fine seems kinda silly.
